Methods: 290 patients who underwent Anderson-Hynes pyeloplasty for ureteropelvic junction obstruction (UPJO) were included in a retrospective analysis. Urine was obtained directly before the renal pelvis was opened, and was carried to the laboratory for bacterial culture. Clinical features were analyzed to evaluate risk factors for bacteriuria or funguria by comparing patients whose urine yielded positive cultures to those whose urine cultures were negative for bacteria or yeast. Results: Eighteen patients (6.2%) had positive urine cultures, including six cultures positive for Escherichia coli (E. coli), four for Pseudomonas aeruginosa, three for klebsiella pneumoniae, one for maltophilia monad, one for Enterococcus faecium, one for Candida albicans, one for Candida parapsilosis, and one for yeast not otherwise specified. Bacteriuria or funguria was significantly correlated with four clinical features: fever, urinary urgency, and history of nephrostomy or pyeloplasty. Conclusions: Bacteriuria or funguria was less common in children with UPJO, and the majority of organisms were identified as Escherichia coli, Pseudomonas aeruginosa, or Klebsiella pneumoniae. Prophylactic antibacterial agents were probably necessary in those patients who had signs of urinary tract infection (UTI), or history of nephrostomy or pyeloplasty.展开更多

We report its management and outcome at Senegal’s main pediatric surgical department. Patients and Methods: We conducted a descriptive review of all patients managed in our pediatric surgical department at Albert Royer National Children’s Hospital Centre from January 1<sup>st</sup>, 2013 to December 31<sup>st</sup>, 2017. Results: Thirty patients were included in our study. The mean age was three years. Males were more affected (sex ratio of 2.75). The prenatal diagnosis was made in 23% of cases using prenatal ultrasonography. An abdominal mass was the circumstance of discovery in 36% of cases, and lumbar contact and renal sloshing were found in 66% of cases. There was no renal function impairment in 93% of cases. Urinary tract infection occurred in 50% of cases. Ultrasonography (100%) and urinary computed tomography (56%) were used to diagnose. A temporary nephrostomy was performed in 23% of cases, and as definitive treatment, an open Anderson-Hynes procedure was performed in 96% as a nephrectomy was made in a patient. Early postoperative complications were encountered in 56% of cases: urinary tract infection (36%), surgical site infection and anastomotic stenosis (6% both), and urinoma and textiloma (both in 3%). A patient died from sepsis. After a mean follow-up of 12 months, no additional complication was reported. Conclusion: Ureteropelvic junction obstruction was frequently diagnosed late, and its management carried unneglectable morbidity in our environment. A laparoscopic approach would be a solution to improve its outcome.展开更多
