[Laparoscopic pyeloplasty]

Abstract

Objectives: To review indications, results and endourologic alternatives to the pyeloplasty technique.

Methods: We describe the surgical technique proposed by Schluesser et al., which was applied to 9 patients in our series. Another 4 patients underwent a simple laparoscopic pyelolisis.

Results: Results obtained with laparoscopic dismembered pyeloplasties are completely comparable with those obtained with the conventional Anderson Hynes Pyeloplasty. Outcomes were very favourable in 7/9 patients in the series; another one shows a discrete improvement and the other one did not return for control. Is does not happen the same with pyelo-ureterolysis. Two of them had a good outcome, other two remain the same, and another one has not had his control yet.

Conclusions: After 8 years, laparoscopic pyeloplasty has consolidated as the elective technique in cases of recoverable hydronephrosis, secondary to crossing vessels or which have a redundant renal pelvis. A few important modifications to the technique have been proposed; exceptions are that it can also be done by retroperitoneoscopy and that in some cases equally good results may be obtained with the Fenger's laparoscopic pyeloplasty.
