ABSTRACT
Hydronephrosis is defined as aseptic distension of the renal calyces and pelvis with urine as a result of partial obstruction of the outflow of urine. It is a clinical condition which is caused by dilatation of the renal collecting system most frequently caused by incomplete or complete obstruction. Although this condition is quite common yet its incidence and prevalence, aetiology, diagnosis and management is less commonly reported in literature especially in context with adults and non-pregnant women. This prospective study was conducted to evaluate the etiology, classify causes of hydronephrosis and to study common clinical presentation of Hydronephrosis. hydronephrosis was seen as a highly male dominant disease with renal calculi as the major aetiology and BPH and VUR being age-associated risk factors. Aetiology based management of hydronephrosis yielded good outcome. The present study is perhaps the first detailed clinco-pathological profile of hydronephrosis.
