Methods: Retrospective analysis of the clinical data of 68 patients with benign prostatic hyperplasia and underactive detrusor muscle contractility treated by our department from July 2021 to July 2022. The above patients all met the diagnosis of benign prostatic hyperplasia, excluding prostate cancer and urethral stricture. Urodynamics showed a decrease in the contractile force of the bladder detrusor muscle, and the surgical equipment used Olympus bipolar plasma resection equipment method. Divide the above patients into two groups: the experimental group of 34 patients who underwent transurethral plasma enucleation of the prostate and the control group of 34 patients who underwent transurethral plasma resection of the prostate. Evaluate the preoperative clinical baseline level and postoperative observation indicators of the two groups of patients, and compare the statistical differences between the two groups. Results: Both groups of patients successfully completed the surgery, and there were no serious complications such as rectal or bladder perforation during the surgery, with less bleeding. The postoperative QOL, IPSS, Qmax, and residual urine volume of patients undergoing transurethral plasma enucleation and resection of the prostate were significantly improved compared to those before surgery (P 0.05). Conclusion: Transurethral enucleation of the prostate has good efficacy and safety in the treatment of benign prostatic hyperplasia combined with weakened detrusor muscle contractility. Compared with traditional electric resection surgery, the efficacy is more significant. In terms of the main complications of the surgery, although there are slightly more patients with temporary urinary incontinence after prostate enucleation, there is no statistically significant difference compared to after electric resection, and they can recover to normal in the short term.展开更多

Transurethra...Benign prostatic hyperplasia (BPH) is highly prevalent among older men, impacting on their quality of life, sexual function, and genitourinary health, and has become an important global burden of disease. Transurethral plasmakinetic resection of prostate (TUPKP) is one of the foremost surgical procedures for the treatment of BPH. It has become well established in clinical practice with good efficacy and safety. In 2018, we issued the guideline “2018 Standard Edition”. However much new direct evidence has now emerged and this may change some of previous recommendations. The time is ripe to develop new evidence-based guidelines, so we formed a working group of clinical experts and methodologists. The steering group members posed 31 questions relevant to the management of TUPKP for BPH covering the following areas: questions relevant to the perioperative period (preoperative, intraoperative, and postoperative) of TUPKP in the treatment of BPH, postoperative complications and the level of surgeons’ surgical skill. We searched the literature for direct evidence on the management of TUPKP for BPH, and assessed its certainty generated recommendations using the grade criteria by the European Association of Urology. Recommendations were either strong or weak, or in the form of an ungraded consensus-based statement. Finally, we issued 36 statements. Among them, 23 carried strong recommendations, and 13 carried weak recommendations for the stated procedure. They covered questions relevant to the aforementioned three areas. The preoperative period for TUPKP in the treatment of BPH included indications and contraindications for TUPKP, precautions for preoperative preparation in patients with renal impairment and urinary tract infection due to urinary retention, and preoperative prophylactic use of antibiotics. Questions relevant to the intraoperative period incorporated surgical operation techniques and prevention and management of bladder explosion. The application to different populations incorporating the efficacy and safety of TUPKP in the treatment of normal volume (< 80 ml) and large-volume (≥ 80 ml) BPH compared with transurethral urethral resection prostate, transurethral plasmakinetic enucleation of prostate and open prostatectomy;the efficacy and safety of TUPKP in high-risk populations and among people taking anticoagulant (antithrombotic) drugs. Questions relevant to the postoperative period incorporated the time and speed of flushing, the time indwelling catheters are needed, principles of postoperative therapeutic use of antibiotics, follow-up time and follow-up content. Questions related to complications incorporated types of complications and their incidence, postoperative leukocyturia, the treatment measures for the perforation and extravasation of the capsule, transurethral resection syndrome, postoperative bleeding, urinary catheter blockage, bladder spasm, overactive bladder, urinary incontinence, urethral stricture, rectal injury during surgery, postoperative erectile dysfunction and retrograde ejaculation. Final questions were related to surgeons’ skills when performing TUPKP for the treatment of BPH. We hope these recommendations can help support healthcare workers caring for patients having TUPKP for the treatment of BPH.展开更多

We conducted a retrospective analysis of clinical data of BPH patients who received PK-TURP. A total of 1126 BPH patients were divided into AUR （n = 348） and non-AUR groups （n = 778）. After the urethral catheters were removed, the urine white blood cell （WBC） count in the AUR group significantly increased compared with the non-AUR group （P〈 0.01）. However, there was no significant difference in international prostate symptom score, painful urination, and maximal urinary flow rate. The duration of hospitalization of the AUR group was longer than that of the non-AUR group （P 〈 0.001）. A total of 87.1% （303/348） patients in the AUR group and 84.1% （654/778） patients in the non-AUR group completed all of the postoperative follow-up visits. The incidence of urinary tract infection in the AUR group within 3 months after surgery was significantly higher than that in the non-AUR group （P 〈 0.01）. The incidence of temporary urinary incontinence in the AUR group did not exhibit significant difference. During 3-12 months after surgery, there were no significant differences in major complications between the two groups. Multivariate regression analyses showed that age, postvoid residual, maximal urinary flow rate, diabetes, and hypertension, but not the presence of AUR, were independent predictors of IPSS post-PK-TURP. In conclusion, immediate PK-TURP surgery on patients accompanied by AUR was safe and effective.展开更多

Two hundred and sixty-seven cases of BPO performed PKEP from July 2008 to June 2009 were retrospectively analyzed. Five-year postoperative data were collected and compared with the preoperative data. According to the urodynamic results, the patients were divided into involuntary detrusor contraction （IDC） group （n = 95） and no IDC group （n = 172） preoperatively; the patients with IDC were divided into IDC-persistent group （n = 33） and IDC-resolved group （n = 62） after PKER The predictors of persistent IDC were analyzed. Compared with the preoperative data, the 5-year postoperative data showed that the IDC rate was lower （P --- 0.000）, Overactive Bladder Symptom Score （OABSS） was lower （P = 0.000）, maximum cystometric capacity （MCC） was larger （P= 0.000）, Prostate volume （PV） was smaller （P= 0.000）, and prostate-specific antigen （PSA） was lower （P= 0.000）. Compared with the no IDC group, the IDC group showed that the age was older （P = 0.016）, MCC was smaller （P = 0.004）, PSA was higher （P = 0.016）, and Chronic Inflammation rate was higher （P = 0.004）. Compared with IDC-resolved group after PKER IDC-persistent group showed that the age was older （P = 0.019）, MCC was smaller （P = 0.000）, PSA was higher （P = 0.013）, and Chronic Ihflammation rate was higher （P = 0.032）. The present study shows that the storage symptoms are still needed to be focused on after PKER The advanced patient age, MCC, PSA, and chronic inflammation may be the important clinical predictors of persistent IDC.展开更多
