The selection was done first by the title and abstract screening and then by full-text assessment for eligibility. Only randomized controlled trials or cohort studies in patients with hydronephrosis secondary to obstructive urolithiasis that presented comparative data between PCN and RUS placement concerning at least one of the defined outcome measures were included. Lastly, MEDLINE database and PubMed platform were screened again using the same terms, from June 2019 until November 2022.Results: Of 556 initial articles, seven were included in this review. Most works were considered of moderate-to-high quality. Three studies regarding QoL showed a tendency against stenting, even though only one demonstrated statistically significant negative impact on overall health state. Two works reported significantly more post-intervention urinary symptoms in stenting patients. One article found that PCN is a significant predictor of spontaneous stone passage, when adjusted for stone size and location. Findings on length of hospital stays were not consistent among articles.Conclusion: PCN appears to be the intervention better tolerated, with less impact on the patient’s perceived QoL and less post-operative urinary symptoms, in comparison with RUS. Nevertheless, further studies with larger samples and a randomized controlled design are suggested.展开更多

There is currently no consensus on the ideal treatment or treatment pathway for ureteral obstruction owing, in part, to the varied etiologies of obstruction and diversity of institutional practices. Additionally, different clinicians such as internists, urologists, oncologists and radiologists are often involved in the care of patients with ureteral obstruction and may have differing opinions concerning the best management strategy. The purpose of this manuscript was to review available literature that compares percutaneous nephrostomy placement vs ureteral stenting in the management of ureteral obstruction from both benign and malignant etiologies.展开更多

Percutaneous nephrostomy for percutaneous nephrolithotomy (PNL) was performed in patients with various renal, perinephric and bladder diseases (n=79). The tract establishment, operation duration and complications were observed and the efficacy was assessed. The results showed that the tracts were successfully established in 79 cases. The operation lasted 4–20 min. 12F–16F single tract was established in nephrohydrop patients and 16F–20F single or multiple tracts were established in patients with pyonephrosis, renal cortical abscess, renal cyst and perinephric abscess. During dilation, no leakage of liquor puris was noted. Establishment of 18F single tract was achieved in one urinoma patient. In two patients with foreign body in kidney, the foreign bodies were removed via established 14F single tract. 18F tracts were established in 2 patients with bladder contracture, which was followed by the placement of 16F balloon urethral catheter for drainage. No complications, such as massive bleeding, intestinal injury and spreading of infection took place in our series. All the patients were followed up for 2–12 months. No long-term complications such as dropping of drainage tube occurred. It is concluded that as a minimally invasive technique, percutaneous nephrostomy has the advantages of convenience, simplicity and causing less complications and can be used for various urologic diseases.展开更多

Materials & Methods: This prospective comparative study intended to compare the outcomes between PCNL without nephrostomy tube and PCNL with nephrostomy tube. A total of 50 cases of renal stone disease planned for PCNL in Dhaka Medical College Hospital from July 2015 to June 2017, were included in this study according to the statistical calculation. Cases were randomly allocated to group A (PCNL without nephrostomy tube) and group B (PCNL with nephrostomy tube). Each group consisted of 25 patients. The outcome variables were post operative pain, requirement of analgesic, leakage of urine and post operative hospital stay. Data were analyzed and compared by statistical tests. Results: No significant differences were found regarding age (p = 0.95), sex (p = 0.55) and operation time (p = 0.36) between two groups. Post operative pain (p p p p Conclusions: Percutaneous nephrolithotomy without nephrostomy tube is better than percutaneous nephrolithotomy with nephrostomy tube in selective cases. It significantly reduces post operativepain, analgesic requirement and postoperative hospital stay. So percutaneous nephrolithotomy without nephrostomy tube is safe and effective.展开更多

Two groups were formed; Group A(16 patients) was treated with an ultrasound-guided percutaneous release of the affected A1 pulley under local anesthesia. Group B(16 patients) underwent an open surgical release of the A1 pul ey, through a 10-15 mm incision. Patients were assessed pre- and postoperatively(follow-up:2,4 and 12 wk) by physicians blinded to the procedures. Treatment of triggering(primary variable of interest) was expressed as the "success rate" per digit. The time for taking postoperative pain killers, range of motion recovery, QuickD ASH test scores(Greek version), return to normal activities(including work), complications and cosmetic results were assessed.RESULTS The success rate in group A was 93.75%(15/16) and in group B 100%(16/16). Mean times in group A patients were 3.5 d for taking pain killers, 4.1 d for returning to normal activities, and 7.2 and 3.9 d for complete extension and flexion recovery, respectively. Mean Quick DASH scores in group A were 45.5 preoperatively and, 7.5, 0.5 and 0 after 2, 4, and 12 wk postoperatively. Mean times in group B patients were 2.9 d for taking pain killers, 17.8 d for returning to normal activities, and 5.6 and 3 d for complete extension and flexion recovery. Mean QuickD ASH scores in group B were 43.2 preoperatively and, 8.2, 1.3 and 0 after 2, 4, and 12 wk postoperatively. The cosmetic results found excellent or good in 87.5%(14/16) of group A patients, while in 56.25%(9/16) of group B patients were evaluated as fair or poor.CONCLUSION Treatment of the trigger finger using ultrasonography resulted in fewer absence of work days, and better cosmetic results, in comparison with the open surgery technique. It is a promising method that represents excellent results without major complications, so that it could be possibly be established as a first-line treatment in the trigger finger's disease.展开更多

Percutaneous nephrolithotomy(PNL) is currently the first-line recommended treatment for large kidney stones ≥ 20 mm and it has an excellent stone-free rate for large kidney stones. However, its invasiveness is not negligible considering its major complication rates. Staged f URS is a practical treatmentfor such large kidney stones because f URS has a minimal blood transfusion risk, short hospitalization and few restrictions on daily routines. However, as the stone size becomes larger, the stone-free rate decreases, and the number of operations required increases. Therefore, in our opinion, staged f URS is a practical option for kidney stones 20 to 40 mm. Miniaturized PNL combined with f URS should be considered to be a preferred option for stones larger than 40 mm. Moreover, URS is an effective treatment for multiple upper urinary tract stones. Especially for patients with a stone burden < 20 mm, URS is a favorable option that promises a high stone-free rate after a single session either unilaterally or bilaterally. However, for patients with a stone burden ≥ 20 mm, a staged operation should be considered to achieve stone-free status.展开更多

METHODS: Patients who were diagnosed with unresectable, locally advanced or metastatic PC between February 2006 and September 2011 were selected for this retrospective study. FNA biopsy for pancreatic tumors had been performed percutaneously under extracorporeal ultrasound guidance until October 2009; then, beginning in November 2009, EUS-FNA has been performed. We reviewed the complete medical records of all patients who met the selection criteria for the following data: sex, age, location and size of the targeted tumor, histological and/or cytological findings, details of puncture procedures, time from day of puncture until day of definitive diagnosis, and details of severe adverse events. RESULTS: Of the 121 patients who met the selection criteria, 46 had a percutaneous biopsy (Group A) and 75 had an EUS-FNA biopsy (Group B). Adequate cytological specimens were obtained in 42 Group A patients (91.3%) and all 75 Group B patients (P=0.0192), and histological specimens were obtained in 41 Group A patients (89.1%) and 65 Group B patients (86.7%). Diagnosis of malignancy by cytology was positive in 33 Group A patients (78.6%) and 72 Group B patients (94.6%) (P=0.0079). Malignancy by both cytology and pathology was found in 43 Group A (93.5%) and 73 Group B (97.3%) patients. The mean period from the puncture until the cytological diagnosis in Group B was 1.7 d, which was significantly shorter than that in Group A (4.1 d) (P < 0.0001). Severe adverse events were experienced in two Group A patients (4.3%) and in one Group B patient (1.3%). CONCLUSION: EUS-FNA, as well as percutaneous needle aspiration, is an effective modality to obtain cytopathological confirmation in patients with advanced PC.展开更多

The popularization of ultrasound in urological practice has contributed to changing habits by making the procedures safer and more effective. The objective of this work was to study the technical aspects, indications and results of minimally invasive urological procedures guided by ultrasound. Material and methods: This was a prospective descriptive study lasting 1 year from January to December 2023 at the Médicis clinic in Conakry. Results: We carried out 126 ultrasound-guided urological interventions in one year, including 6 percutaneous nephrostomies (NPC), one renal cyst puncture-aspiration-sclerotherapy, 102 prostate biopsies, 5 drainages by transrectal aspiration of prostatic abscesses, 10 placements of cystostomy probes. Suprapubic, 2 puncture-aspiration-sclerotherapies for vaginal hydroceles. The average age of our patients was 69 years and the predominant age range was 61 - 70. The majority of our patients were male (97.61%) with a sex ratio of 41 men to one woman. Ultrasound-guided urological interventions were for diagnostic purposes (80.95%), for therapeutic purposes (15.77%) and for diagnostic and therapeutic purposes (3.96%). The indications for ultrasound-guided urological interventions were dominated by prostate pathologies (84.91%). The majority of interventions were performed rectally (84.92%) versus (13.43%) abdominally and only 1.58% scrotalally. All procedures were performed in B-ultrasound mode under local anesthesia and on an outpatient basis. For therapeutic interventions, the patients were seen again one month after the procedure, the clinical examination and ultrasound control found the evolution to be favorable. Conclusion: ultrasound is useful in urological practice for guiding minimally invasive interventions. The indications for ultrasound-guided procedures in urology are dominated by prostate pathologies. These procedures are safe and effective with fewer complications. Interventional ultrasound must be further integrated into the habits of urologists.展开更多

文摘Percutaneous nephrostomy was applied in some other urologic diseases and the efficacy was evaluated. Percutaneous nephrostomy for percutaneous nephrolithotomy (PNL) was performed in patients with various renal, perinephric and bladder diseases (n=79). The tract establishment, operation duration and complications were observed and the efficacy was assessed. The results showed that the tracts were successfully established in 79 cases. The operation lasted 4–20 min. 12F–16F single tract was established in nephrohydrop patients and 16F–20F single or multiple tracts were established in patients with pyonephrosis, renal cortical abscess, renal cyst and perinephric abscess. During dilation, no leakage of liquor puris was noted. Establishment of 18F single tract was achieved in one urinoma patient. In two patients with foreign body in kidney, the foreign bodies were removed via established 14F single tract. 18F tracts were established in 2 patients with bladder contracture, which was followed by the placement of 16F balloon urethral catheter for drainage. No complications, such as massive bleeding, intestinal injury and spreading of infection took place in our series. All the patients were followed up for 2–12 months.

文摘Objectives: To compare the outcomes of Percutaneous Nephrolithotomy (PCNL) with or without nephrostomy tube. Materials & Methods: This prospective comparative study intended to compare the outcomes between PCNL without nephrostomy tube and PCNL with nephrostomy tube. A total of 50 cases of renal stone disease planned for PCNL in Dhaka Medical College Hospital from July 2015 to June 2017, were included in this study according to the statistical calculation. Cases were randomly allocated to group A (PCNL without nephrostomy tube) and group B (PCNL with nephrostomy tube). Each group consisted of 25 patients. The outcome variables were post operative pain, requirement of analgesic, leakage of urine and post operative hospital stay. Data were analyzed and compared by statistical tests. Results: No significant differences were found regarding age (p = 0.95), sex (p = 0.55) and operation time (p = 0.36) between two groups. Post operative pain (p p p p Conclusions: Percutaneous nephrolithotomy without nephrostomy tube is better than percutaneous nephrolithotomy with nephrostomy tube in selective cases. It significantly reduces post operativepain, analgesic requirement and postoperative hospital stay. So percutaneous nephrolithotomy without nephrostomy tube is safe and effective.
文摘AIM To investigate the effectiveness of ultrasound-guided release of the first annular pulley and compare results with the conventional open operative technique.METHODS In this prospective randomized, single-center, clinical study, 32 patients with trigger finger or trigger thumb, grade Ⅱ-Ⅳ according to Green classification system, were recruited. Two groups were formed; Group A(16 patients) was treated with an ultrasound-guided percutaneous release of the affected A1 pulley under local anesthesia. Group B(16 patients) underwent an open surgical release of the A1 pul ey, through a 10-15 mm incision. Patients were assessed pre- and postoperatively(follow-up:2,4 and 12 wk) by physicians blinded to the procedures. Treatment of triggering(primary variable of interest) was expressed as the "success rate" per digit. The time for taking postoperative pain killers, range of motion recovery, QuickD ASH test scores(Greek version), return to normal activities(including work), complications and cosmetic results were assessed.RESULTS The success rate in group A was 93.75%(15/16) and in group B 100%(16/16). Mean times in group A patients were 3.5 d for taking pain killers, 4.1 d for returning to normal activities, and 7.2 and 3.9 d for complete extension and flexion recovery, respectively. Mean Quick DASH scores in group A were 45.5 preoperatively and, 7.5, 0.5 and 0 after 2, 4, and 12 wk postoperatively. Mean times in group B patients were 2.9 d for taking pain killers, 17.8 d for returning to normal activities, and 5.6 and 3 d for complete extension and flexion recovery. Mean QuickD ASH scores in group B were 43.2 preoperatively and, 8.2, 1.3 and 0 after 2, 4, and 12 wk postoperatively. The cosmetic results found excellent or good in 87.5%(14/16) of group A patients, while in 56.25%(9/16) of group B patients were evaluated as fair or poor.CONCLUSION Treatment of the trigger finger using ultrasonography resulted in fewer absence of work days, and better cosmetic results, in comparison with the open surgery technique. It is a promising method that represents excellent results without major complications, so that it could be possibly be established as a first-line treatment in the trigger finger's disease.
文摘Flexible ureteroscopy(f URS) has become a more effective and safer treatment for whole upper urinary tract stones. Percutaneous nephrolithotomy(PNL) is currently the first-line recommended treatment for large kidney stones ≥ 20 mm and it has an excellent stone-free rate for large kidney stones. However, its invasiveness is not negligible considering its major complication rates. Staged f URS is a practical treatmentfor such large kidney stones because f URS has a minimal blood transfusion risk, short hospitalization and few restrictions on daily routines. However, as the stone size becomes larger, the stone-free rate decreases, and the number of operations required increases. Therefore, in our opinion, staged f URS is a practical option for kidney stones 20 to 40 mm. Miniaturized PNL combined with f URS should be considered to be a preferred option for stones larger than 40 mm. Moreover, URS is an effective treatment for multiple upper urinary tract stones. Especially for patients with a stone burden < 20 mm, URS is a favorable option that promises a high stone-free rate after a single session either unilaterally or bilaterally. However, for patients with a stone burden ≥ 20 mm, a staged operation should be considered to achieve stone-free status.
文摘AIM: To clarify the effectiveness and safety of endo- scopic ultrasound-guided fine-needle aspiration (EUS-FNA) for the diagnosis of pancreatic cancer (PC). METHODS: Patients who were diagnosed with unresectable, locally advanced or metastatic PC between February 2006 and September 2011 were selected for this retrospective study. FNA biopsy for pancreatic tumors had been performed percutaneously under extracorporeal ultrasound guidance until October 2009; then, beginning in November 2009, EUS-FNA has been performed. We reviewed the complete medical records of all patients who met the selection criteria for the following data: sex, age, location and size of the targeted tumor, histological and/or cytological findings, details of puncture procedures, time from day of puncture until day of definitive diagnosis, and details of severe adverse events. RESULTS: Of the 121 patients who met the selection criteria, 46 had a percutaneous biopsy (Group A) and 75 had an EUS-FNA biopsy (Group B). Adequate cytological specimens were obtained in 42 Group A patients (91.3%) and all 75 Group B patients (P=0.0192), and histological specimens were obtained in 41 Group A patients (89.1%) and 65 Group B patients (86.7%). Diagnosis of malignancy by cytology was positive in 33 Group A patients (78.6%) and 72 Group B patients (94.6%) (P=0.0079). Malignancy by both cytology and pathology was found in 43 Group A (93.5%) and 73 Group B (97.3%) patients. The mean period from the puncture until the cytological diagnosis in Group B was 1.7 d, which was significantly shorter than that in Group A (4.1 d) (P < 0.0001). Severe adverse events were experienced in two Group A patients (4.3%) and in one Group B patient (1.3%). CONCLUSION: EUS-FNA, as well as percutaneous needle aspiration, is an effective modality to obtain cytopathological confirmation in patients with advanced PC.

文摘Objective:Complex ureteral obstruction is refractory to conventional urological intervention.This report describes a case of laparoscopic ureterolysis with simultaneous ureteroscopy and percutaneous nephroscopy for treating complex ureteral obstruction.Methods:Right-side multiple ureteral stones and complicating ureteral obstruction failed an initial attempt of ureteroscopy lithotripsy with simultaneous percutaneous nephroscopy in a 23-year-old male.Laparoscopic ureterolysis with ureteroscopy and percutaneous nephroscopy was used simultaneously to dissect the periureteral adhesions with the patient placed in the Galdakao-modified supine Valdivia position.The ureter was incised to allow the insertion of a ureteral catheter through the twisted ureter,and a guide wire was advanced into the pelvis using ureteroscopy.A double-J stent was placed into the right-side ureter using antegrade percutaneous nephroscopy.Results:The laparoendoscopic procedure lasted 330 min with an estimated bleeding volume of 100 mL.The patient underwent an uneventful postoperative course,and postoperative followup radiography confirmed good positioning of the double-J stent.The double-J stent was removed 3 months after operation.The patient remained asymptomatic within a 13-month follow-up period.Conclusion:Laparoscopic ureterolysis with simultaneous ureteroscopy and percutaneous nephroscopy is an effective and safe treatment option for complex ureteral obstruction.
文摘Introduction: Minimally invasive urological interventions have long been practiced blindly in our context. The popularization of ultrasound in urological practice has contributed to changing habits by making the procedures safer and more effective. The objective of this work was to study the technical aspects, indications and results of minimally invasive urological procedures guided by ultrasound. Material and methods: This was a prospective descriptive study lasting 1 year from January to December 2023 at the Médicis clinic in Conakry. Results: We carried out 126 ultrasound-guided urological interventions in one year, including 6 percutaneous nephrostomies (NPC), one renal cyst puncture-aspiration-sclerotherapy, 102 prostate biopsies, 5 drainages by transrectal aspiration of prostatic abscesses, 10 placements of cystostomy probes. Suprapubic, 2 puncture-aspiration-sclerotherapies for vaginal hydroceles. The average age of our patients was 69 years and the predominant age range was 61 - 70. The majority of our patients were male (97.61%) with a sex ratio of 41 men to one woman. Ultrasound-guided urological interventions were for diagnostic purposes (80.95%), for therapeutic purposes (15.77%) and for diagnostic and therapeutic purposes (3.96%). The indications for ultrasound-guided urological interventions were dominated by prostate pathologies (84.91%). The majority of interventions were performed rectally (84.92%) versus (13.43%) abdominally and only 1.58% scrotalally. All procedures were performed in B-ultrasound mode under local anesthesia and on an outpatient basis. For therapeutic interventions, the patients were seen again one month after the procedure, the clinical examination and ultrasound control found the evolution to be favorable. Conclusion: ultrasound is useful in urological practice for guiding minimally invasive interventions. The indications for ultrasound-guided procedures in urology are dominated by prostate pathologies. These procedures are safe and effective with fewer complications. Interventional ultrasound must be further integrated into the habits of urologists.
