Flexible cystoscope:an adjuvant device to help the surgical management of complex renal calculi / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the use of flexible cystoscope in the surgical management of complex renal calculi. Methods Flexible cystoscope and a set of stone baskets were used to help the surgical of complex renal calculi via the renal pelvis incision or the dilated ureter during operation.A pyelostomy with the use of a Foley's catheter was carried out if necessary and the residual stones could be removed via the pyelostomy tract later on. Results 31 cases of complex renal stones have been surgically treated.Flexible cystostomy was used intraoperatively in 11,postoperatively for the removal of residual stones in 16 and being used both intra and postoperatively in 4.A total of 106 stones have been removed.26 patients ( 83.9 %) have been free from any stone.2(6.4%) have undergone ESWL followed by flexible cystoscopy to remove the residual stones.3 patients (9.7%),however,still had residual stones in spite of the above procedure. Conclusions Flexible cystoscopy as an adjuvant procedure is an effective means in the surgical treatment of complex renal calculi especially for the removal of residual stones.The procedure is simple,safe and less expansive.
