Study design 

Descriptive case series.

Place & Duration of study

Surgical C Unit, Hayatabad Medical Complex Peshawar, from January 2020 to December 2021.

Methodology

A total of 25 patients of either gender with unilateral hydronephrosis due to pelvi-ureteric junction obstruction were included. Patients with hydronephrosis due to vesico-ureteric reflux, obstruction secondary to external compression and redo pyeloplasty were excluded. These patients underwent open Anderson Hynes pyeloplasty. Postoperative outcome was recorded and analyzed using SPSS version 16.

Results

The age of the patients was from 5-years to 35-years with the mean age of 22+5 year. There were 20 (80%) male and 5 (20%) female patients. Left side was involved in 17 (68%) patients. Presenting complaints were flank pain in 23 (92%), swelling in lumbar region in 5 (20%) and feeling of heaviness in the flank in 7 (28%) patients. Postoperative morbidity included pyrexia in 5 (20%), anastomotic urinary leak in 3 (12%) and urinoma formation in 2 (8%) patients. Re-stenosis of pelvi-ureteric anastomosis occurred in one (4%) patient who required redo surgery. The overall success rate was 96%.
