ABSTRACT
To evaluate the feasibility of the ureteroscope versus the use of cystoscope to introduce the ureteric guide wire. This study was conducted on 50 patients [100 units]. They were divided into two groups, group A [50 units] with normal ureters in one side as seen in IVU and group B [50 units] with pathology either stricture or stone ureter in the other side. After initial cystoscopic evaluation and identification of both ureteric orifices, the cystoscope and/or ureteroscope were used to introduce the guide wire in group A ureteroscopy was successful in 100% of the cases [25 units] as initial tool, while with the use of the cystoscope it is only 76% [18 out of 25] which increased to 96% after the use of ureteroscope to introduce the guide wire. In group B with the use of ureteroscope in 25 pathological ureters, it is successful in 92% of the cases [23/ 25] while with the use of cystoscope it is only 60% [15/ 25]. With the aid of the ureterpscope in the remaining failed cases the success rate was increased to 80% [20/25] and complete failure in 5 cases due to massive trauma to the ureter from multiple trials of blind introduction of the guide wire through the cystoscope. Introduction of the ureteric guide wire is essential step in ureteroscopy as with its failure all the procedure will fail. So, simple and easy introduction of the guide wire through the cystoscope was tried first, if failed, multiple trials is not recommended and it is better to use the ureteroscope to introduce it under vision better than blind trials avoiding trauma to the ureter
