Abstract

Aim: To evaluate the treatment of renal pelvic stones with rigid ureterorenoscopy.

Meterial and Methods: Total of 13 patients were evaluated between January 2009 and March 2010. Stones in all patients were equal to or less than 2 cm. The patients who refused ESWL (Extracorporeal Shock Wave Lithotripsy) treatment or those who have failed in ESWL treatment were included in the study. Other treatment options were explained to patients. Rigid ureterorenoscopy was performed with pneumatic lithotripter. Double-J uretheral stent was applied in all the cases.

Results: The mean age of the patients was 53±4.23 years (minimum: 33 and maximum: 73 years). The average operation time was 42.3±14.2 minutes (minimum: 35 and maximum: 55 minutes). Small stone fragments were passed spontaneously in six patients in three weeks. Stone way was created in three patients and we performed re-ureterorenoscopy in these cases after two weeks. The fragments of small stones migrated to the renal calyxes in three cases. Stone-free rate was 77% after all the procedures. Observed complications: hematuria in two patients cases in postoperative two days (no blood transfusion needed); high fever in one patient and severe dysuria in one patient.

Conclusion: There are treatment options such as percutaneous nephrolithotomy, flexible ureterorenoscopy, open surgery for treatment of renal stones. The rigid ureterorenoscopy can be considered as a low cost and effective treatment in the renal pelvic stones.
