Popis: Summary Introduction Failed pyeloplasty procedures are caused by large amounts of scarring, and peripelvic fibrosis. This finding has been associated with urinary extravasations to the operation, urosepsis or an excessive tissue reaction. The treatment options for secondary UPJO (Ureteropelvic Junction Obstruction) are the same with the options for primary procedures: in cases of very poor renal function, various pyeloplasty forms (open and laparoscopic), and ureterocalicostomy or sometimes nephrectomy may be considered in severe renal function loss. Whereas, endoscopic treatment can be considered in elective cases. Study design A total of 46 young patients who underwent endopyelotomy due to secondary ureteropelvic obstruction between January 2013 and September 2018 were included in the study. Patients underwent semirigid URS (Ureterorenoscopy) guided laser endopyelotomy until July 2015, and the patients had flexible URS guided laser endopyelotomy since July 2015. Results The mean age of the patients was found as 17.7 ± 4.2 and 16.9 ± 5.7 years in the SURSLE (Semirigid Ureterorenoscopy Laser Endopyelotomy), and FURSLE (Flexible Ureterorenoscopy Laser Endopyelotomy) groups, respectively. Success of the procedure was confirmed in 20 (83%) patients in the SURSLE group, and 19 (86%) patients in the FURSLE group who had no obstructive symptoms based on USG, GFR and excretion curves on the renogram ordered in the 24th month. Four (16%) patients in the SURSLE group, and 3 (14%) patients in the FURSLE group were accepted as failed, their treatments were arranged for additional surgical procedures, and these patients were taken under the follow-up protocol. Discussion This is one of the first studies comparing endopyelotomy with semirigid URS and flexible URS in patients with ureteropelvic stenosis. Long-term results with a large series of patients are not known, and our approach can be considered only as an individual method. There are different treatment options in UPJO. The use of fluoroscopy has advantages in endourologic operations. Therefore, lower radiation exposure can be a rational approach for protecting a person. Similarly, providing necessary protection also for physicians and operating room personnel is essential. In our study, shorter fluoroscopy time with SURSLE provided an advantage over FURSLE in terms of radiation exposure. Conclusion Of semirigid and flexible URS techniques that have no superiority over each other in terms of success, preferring semi-rigid URS guided laser endopyelotomy with lower ionizing radiation used, is more rational.
