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

Abstract EN

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.
