Laparoscopic Pyeloplasty for Ureteropelvic Junctions Obstruction in Adults: 6 Years' Experience in One Center

OBJECTIVE: Ureteropelvic junction obstruction (UPJO) is a common cause of symptomatic ureteral obstruction. The aim of this study is to assess the outcome of laparoscopic pyeloplasty in patients with UPJO.

PATIENTS AND METHODS: Medical reports of 47 UPJO patients treated with laparoscopic pyeloplasty were retrospectively analysed. All patients were recruited from our center in the period 2004-2011.

RESULTS: We evaluated 47 patients. Mean age was 36 years and mean hospital stay 3.6 days. 42 (79%) of the patients had pain and 46 (98%) were diagnosed with hydronephrosis. 19 patients (40%) had a renal function below 40% of the affected kidney and 49% had impaired renal scan drainage. Postoperative significant improvement in pain score and renal scan drainage was found in 92% and 47% of the patients, respectively. Improvement of renal function > 10% was found in 11 patients (23%); the function remained stable in 31 patients (66%) and deteriorated > 10% in 5 patients (11%). We found no correlation between sex or age and the outcome.

CONCLUSION: Laparoscopic pyeloplasty for UPJO leads to relief of pain and preserved or improved renal function in the majority of the patients. Overall laparoscopic pyeloplasty is an efficient treatment for UPJO.
