Laparoscopic Retroperitoneal Ureterolithotomy / 대한비뇨기과학회지

ABSTRACT

PURPOSE: In the era of shock wave lithotripsy (SWL) and ureteroscopy, the majority of ureter stones are successfully managed with these less invasive treatment modalities. However, open ureterolithotomy still has a role in special situations. The efficacy of a laparoscopic retroperitoneal ureterolithotomy for large impacted ureter stones indicated for open ureterolithotomy is reported. MATERIALS AND MTHODS Between February 1998 and December 1999, laparoscopic retroperitoneal ureterolithotomy for proximal ureter stones was performed in 5 patients who required an open ureterolithotomy. The mean size of the stones was 15mm, all of which were tightly impacted in the ureteral lumen and were associated with marked hydronephrosis. RESULTS: All but the initial operation was performed successfully via the retroperitoneal approach. Open conversion was needed in the first patient because of inexperience and the lack of anatomic perception. The mean operation time and estimated blood loss was 122 minutes and < or =50ml, respectively. A transfusion was not needed in any of the patients. Postoperative pain was well controlled with 175mg of Ketoprofen. The mean postoperative length of hospital stay was 6.3 days. There were no significant intraoperative or postoperative complications. CONCLUSIONS: A laparoscopic retroperitoneal ureterolithotomy can be considered as an alternative to conventional ureterolithotomy when open surgery is indicated.
