Study Type – Therapy (case series) Level of Evidence 4 OBJECTIVE • To evaluate the functional and morphological outcome after open pyeloplasty for ureteropelvic junction obstruction (UPJO) with huge renal pelvis. PATIENTS AND METHODS • A retrospective review of all cases who underwent pyeloplasty for huge renal pelvis was conducted. • Records were evaluated with respect to age at presentation, preoperative imaging, surgical details and postoperative course. Patients were followed up regularly for both functional and morphological outcome. • Success was defined as both symptomatic relief and radiographic resolution of obstruction at last follow‐up. RESULTS • Between 1998 and 2008, 526 cases of primary UPJO underwent open dismembered pyeloplasty at our centre. • Of these patients, 41 (8%) had UPJO with huge renal pelvis. • No perioperative complications were encountered in the study group. Mean (range) follow‐up was 34 (18–84) months and nine patients were lost to follow‐up. The overall success rate was 91%. • Two patients underwent redo pyeloplasty, whereas secondary nephrectomy was necessary in one. • Improvement of hydronephrosis was evident in all patients, except in three patients who underwent secondary procedures. • However, persistent obstruction on diuretic renography was seen in most cases (65%). CONCLUSIONS • Open pyeloplasty for huge pelvis UPJO is feasible with a high success rate. • Varying degrees of hydronephrosis and radiological obstruction after pyeloplasty are not uncommon. • Nephrectomy is rarely indicated in cases with severely deteriorated renal function.
