Unilateral Hydronephrosis- a Clinical Study

Bachground: Unilateral obstructions of ureter either due to extramural, or intramural, and or intraluminal lead to unilateral hydronephrosis. Ureteral obstruction, partial or complete, produces a progressive disease in excretory functions of the kidneys with subsequent destruction of renal parenchyma. Material and Methods: 30 cases of unilateral hydronephrosis who fulfilled the inclusion and exclusion criteria were admitted to our hospital, investigated and treated thoroughly. Results: 60% of patients had ureteric calculi and 30% with Pelviureteric junction obstruction. More than 85% patients presented with pain abdomen and mass were palpable in 13.3%. Ultrasound abdomen was diagnostic in 20 cases with ureteric calculi and 10 cases with Pelviureteric junction obstruction. Among 20 cases of ureteric calculi, open procedure was done in 4 cases and endoscopic surgery in 16 cases. Pyeloplasty was performed in 10 cases of Pelviureteric junction obstruction. Conclusion: Males from lower socio-economic status affected during their third decade. Tenderness was prominent clinical sign with pain abdomen, hematuria, frequency and painful micturition as common symptoms. Surgical management turned out to be most effective while few cases were managed by endoscopic intervention.
