[Current role of percutaneous renal surgery at a service of general urology].

OBJECTIVE

To evaluate the utility and need for percutaneous surgery in the General Urology Department according to its applicability and efficacy.

METHODS

40 percutaneous surgery procedures were performed over a period of 11 years (average 3.6 procedures/year), which accounts for 0.60% of all surgical procedures performed. These were carried out for pyelic stone (10), caliceal stone (12), pyelic stone in horseshoe kidney (2), pyelic stone + UPJ stricture (4), UPJ stricture (7), UPJ re-stenosis post-pyeloplasty (1), cystectomy (3), diagnostic percutaneous surgery (1).

RESULTS

Good results were achieved in 89.2% of the cases with lithiasis and there were 3 failed attempts (10.7%). Cystectomy achieved a 100% success rate; residual cavity persists in all the cases but there has been no recurrence at 5 years. Endopyelotomy was successful in 41.6% of the cases and stricture recurred in 58.3%. Overall, there were 4 complications without major consequences, although the procedure could not be completed in two cases.

CONCLUSIONS

Although there is little opportunity to apply the technique, it is currently necessary because it achieves unquestionably good results in specific cases.
