Abstract

  Minimally invasive endoscopic combined intrarenal surgery (mini-ECIRS) was performed by one operator for 59 cases of coral stones in conjunction with transurethral lithotripsy under nephrostomy. We examined its usefulness, safety, and differences compared with conventional mini-ECIRS. Transurethral lithotripsy using a flexible ureteroscope is a surgical procedure performed in many facilities, and nephrostomy is also a procedure performed in daily urological practice. By combining these two, although it is inferior to conventional mini-ECIRS regarding the operative time and hospitalization period, a relatively good stone-free rate can be achieved and the risk of bleeding due to tract creation that makes beginners feel uneasy can be reduced. This time, a relatively good stone-free rate was achieved by performing the operation up to twice for cases with a stone volume of 17 cc or less. For stones over 17 cc, conventional mini-ECIRS using a compressed air crusher may be favorable, but one-surgeon mini-ECIRS may be sufficient for stones under 17 cc.
