Introduction and objectives: Congenital ureteropelvic junction obstruction (UPJO) is the most common cause of hydronephrosis. Management protocols are based on the presence of symptoms and when the patient is asymptomatic the function of the affected kidney determines the line of treatment. Percutaneous nephrostomy (PCN) became a widely accepted procedure in children in the 1990s. The aim of the study was to evaluate the results of performing percutaneous nephrostomy (PCN) in all patients with UPJO and split renal function (SRF) of less than 10% in the affected kidney, because the management of such cases is still under debate. Methods:This prospective clinical trial was carried out at Dhaka Medical College Hospital from January 2014 to December 2016. Eighteen consecutive patients who underwent PCN for the treatment of unilateral UPJO were evaluated prospectively. In these children, ultrasonography was used for puncture and catheter insertion. Local anesthesia with sedation or general anesthesia was used for puncture. Pig tail catheters were employed. The PCN remained in situ for at least 4 weeks, during which patients received low-dose cephalosporin prophylaxis. Repeat renography was done after 4 weeks. When there was no significant improvement in split renal function (10% or greater) and PCN drainage (greater than 200 ml per day) then nephrectomies were performed otherwise pyeloplasties were performed. The patients were followed up after pyeloplasty with renograms at 3 months and 6 months post operatively. Results: All the patients had severe hydronephrosis during diagnosis and 14 patients with unilateral UPJO were improved after PCN drainage and underwent pyeloplasty. The rest four patients that did not show improvement in the SRF and total volume of urine output underwent nephrectomy. In the patients with unilateral UPJO who improved after PCN drainage, the SRF was increased to 26.4% ±8.6% (mean± SD) after four weeks and pyeloplasty was performed. At three and six months follow-up, SRF value was 29.2% ±8.5% and 30.8.2% ±8.8% respectively. Conclusion: Before planning of nephrectomy in poorly functioning kidneys (SRF < 10%) due to congenital UPJO, PCN drainage should be done to asses improvement of renal function.

Introduction: Ureteropelvic junction obstruction is a pathology typically diagnosed in childhood. Nevertheless, some clinically silent cases may be unnoticed until adulthood. Case description: We report the case of a 53-year-old female with hydronephrosis due to ureteropelvic junction stenosis diagnosed in the adulthood, who subsequently developed obstruction with progressive worsening of renal function without symptoms. Conclusion: The natural history of ureteropelvic junction obstruction is still obscure. Diuretic renogram is the gold standard for diagnosis and follow-up of ureteropelvic junction obstruction, but is weak in predicting the evolution of the disease, especially in patients with vague symptoms. Conservative treatment of adult patient with equivocal ureteropelvic junction obstruction seems reasonable, but requires a close clinical follow-up and strict patient compliance in order to promptly identify significant obstruction.

Objective This study aimed to present our experience of concomitant management of renal calculi and recurrent ureteropelvic junction obstruction (UPJO) with percutaneous nephrolithotomy (PCNL) and antegrade balloon dilation. Methods We retrospectively reviewed 31 patients who underwent PCNL and antegrade balloon dilation for treatment of renal calculi and recurrent UPJO. The inclusion criterion was the presence of UPJO after failed pyeloplasty with ipsilateral renal calculi. Success was defined as achievement of both symptomatic and radiographic resolution of any stones and obstruction. Results All operations were successful without grade III or higher postoperative complications. A stone-free status was observed in all patients and the overall success rate of the procedure was 87.1% (27/31). The success rate of the procedure was significantly higher in patients with mild or moderate preoperative hydronephrosis (96%) than in those with high-grade preoperative hydronephrosis (50%). Moreover, the success rate of the procedure was lower in patients with poor preoperative renal function (0%) than in those with good or moderate renal function (93.1%). Conclusion Combined PCNL and antegrade balloon dilation management represents a safe and effective approach for patients with renal calculi and recurrent UPJO after failed pyeloplasty.
