Abstract:
Percutaneous Endopyelotomy is a natural outgrowth of technique developed for percutaneous ureteral and renal stone removal. In it`s comparison to the Davis ureterotomy technique, a rationale for this procedure and explanation for it`s success is provided. Endopyelotomy, which we performed experimentally to prevent recurrent stone formation, has now matured into a viable procedure under the certain guideline. This procedure has become our first choice for secondary ureteropelvic junction obstruction but primary cases were not experienced. Although classical pyeloplasty must be main surgical means to UPJ obstruction, technical and equipmental advanced could be enabled us to perform 8 endopyelotomy. We incised UPJ obstruction in 8 cases with direct vision nephroscope inserted through a percutaneous nephrostomy tract and ureteroscope. In 6 patients, renal calculi were removed endourologically during same and separate session. There were no immediate complication and nephrostogram showed adequate drainage in all cases.
