Background: Duplex kidneys are common developmental renal anomaly with an incidence of 1% in healthy adult population.Adult individuals may present as non-functional moiety, calculus disease or an incidental finding. Duplex kidney is defined as a renal unit comprised of two pelvicalyceal systems. Based on the degree of fusion, it can present as bifid renal pelvis, partial ureteric duplication (Y-shaped ureter), incomplete ureteric duplication with ureters joining near or in bladder wall (V-shaped ureter) and complete ureteric duplication with separate ureteric orifices. The purpose of this study is to retrospectively review the various duplex kidney anomalies and associated pathology.Methods: This is a retrospective study, performed at Department of Urology, Gauhati Medical College Hospital, a tertiary centre, from September, 2018 to August, 2019. Preoperative imaging, plain intravenous urography or computed tomography intravenous urography was done.Results: 29 patients were diagnosed with variants of duplex kidney anomaly. It includes right side, left side and bilateral anomalies. Among all the patients 4 had incidental findings. 16 patients had associated renal or ureteral calculus. 5 patients had associated ureteropelvic junction obstruction while 1 patient had ureterovesical junction stricture. We found single patient in each group of duplex kidney anomaly associated with non-functional moiety with renal cell carcinoma, ureterocele with urothelial malignancy and horseshoe kidney with ureteropelvic junction obstruction respectively.Conclusions: Duplex kidney anomaly in most individuals is of no clinical significance. High index of suspicion along with good quality imaging can accurately detect specific anomaly and associated condition.

Antenatal Hydronephrosis

Objective: Ureteropelvic junction obstruction is the main cause of obstructive antenatal hydronephrosis. Although surgery is the traditional treatment modality, there is still no consensus on surgical indications. We aimed to analyse the patients referred as antenatal hydronephrosis and diagnosed with ureteropelvic junction obstruction with Hydronehprosis Severity Score that has been developed by Babu at al. Method: The patients who were admitted with antenatal hydronephrosis in 2013-2018 and diagnosed as ureteropelvic junction obstruction and followed up in our clinic for at least one year were evaluated. The cases with unilateral hydronephrosis were included. Those with vesicoureteral reflux, horseshoe kidney, hydroureter, ureterovesical junction obstruction were excluded. Renal ultrasonography and nuclear scintigraphy results were re-evaluated. They were grouped as mild (0-4), moderate (5-8) and severe (9-12) based on scoring of three parameters; differantial renal function, drainage curve pattern and US grade. Clinical outcomes were also classified in three groups; resolution (grade 1-no hydronephrosis), persistance (grade 2-3 hydronephrosis) and surgical intervention. The relation between the scores and clinical outcomes were analysed. Results: A total of 57 patients were evaluated. 2 with horseshoe kidney, 4 with vesicoureteralreflux, 7 with bilateral hydronephrosis, 4 with ureteric outlet obstruction, 12 with incomplete records were excluded. Finally, 28 patients were included. Hydronephrosis was resolved in 4 (14.2%), persisted in 5 (17.8%) and surgical intervention was required in 19 (67.8%) patients. 1/5 patients with mild, 15/20 patients with moderate and 3/3 patients with severe HSS underwent surgery. 77.2% of the patients with a total score of ≥6 initially required surgical intervention at their follow-up. Conclusion: HSS may provide a significant predictive value for surgical intervention for the patients classified as “mild” or “severe” at the initial evaluation. In the “moderate” group, the risk increases in the patients with HSS≥6. Existing data should be evaluated with larger case series.

Split Renal Function

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.

Common Cause

Ureteropelvic junction obstruction ( UPJO ) is the most common cause of hydronephrosis in children. Hydronephrosis caused by prolongedUPJO will damaged the kidneys. Early detection needed to avoid the complication. In fact, there are cases which is discovered in older child.Therefore it is necessary to carry out appropriate diagnostic steps and support the management of patients. Radiological examination usingvarious modalities can help diagnose UPJO.
