AB  - Aims:We aimed to compare the efficiency of cold knife urethrotomy andlaser urethrotomy in endoscopic surgery of urethral strictures. Material-Methods:A total of 171 patients were evaluated retrospectively. A 118patients with complete data were divided into two groups (group 1; n= 53 cold knife urethrotomy, group 2; n = 65 laser urethrotomy) inthe study. Length of the stricture, operation time, preoperative andpostoperative 3rd,6thand 12th-monthQmax values, recurrence and the presence of complications (such asbleeding, extravasation, fever etc.) were compared in terms of thetwo groups. Results:The operation time was found to be shorter in patients who underwentcold knife urethrotomy (14.01 ± 3.86 min vs 25.03 ± 4.43 min,p=0.001). The Q max values at the postoperative 3rd,6thand 12thmonths were observed to be higher in patients who underwent laserurethrotomy (p=0.03, p=0.001, p=0.001). At the end of a one-yearfollow-up, recurrence was determined in 28 (52.83%) patients in group1 and 12 (18.46%) patients had a recurrencein group 2 (p=0.01). Nostatistically significant difference was observed between the twogroups in terms of postoperative complications. (p=0.209).Conclusions:In this study, it was determined that laser urethrotomy technique wasa more successful surgical method than cold knife urethrotomy in theendoscopic surgery of urethral strictures as it has higher Qmaxvalues and lower recurrence rate. The results should be supported byprospective, randomized studies.

N2  - Amaç:Üretra darlığının endoskopik cerrahisinde cold knife üretrotomiile laser üretrotominin etkinliğini karşılaştırmayı amaçladık.Materyal-metod:Toplam171 hasta retrospektif olarak değerlerlendirildi. Çalışmakapsamında verileri tam olan 118 hasta 2 gruba ayrıldı (grup 1;n=53 cold knife üretrotomi, grup 2; n= 65 lazer üretrotomi).Darlığın uzunluğu, operasyon süresi, preoperatif  vepostoperatif 3., 6. ve12. aylardaki Qmax değerleri, nüks olupolmadığı ve komplikasyon varlığı (kanama, extravazasyon, ateşgb) açısından iki grup karşılaştırıldı. Bulgular:Operasyon zamanının cold knife üretrotomi yapılan hastalarda dahakısa olduğu görüldü (14.01 ± 3.86 dk vs 25.03 ± 4.43 dk,p=0.001). Postoperatif 3., 6., ve 12. aylardaki Q max değerlerinin lazer üretrotomi yapılan hastalarda daha yüksek olduğu görüldü(p=0.03, p=0.001, p=0.001). Bir yıllık takip sonucunda grup-1' de28 (52.83%) hastada nüks saptanırken, grup-2' de 12 (18.46%)hastada nüks geliştiği gözlendi (p=0.01). Postoperatifkomplikasyonlar açısından her iki grup arasında istatiksel olarakanlamlı fark izlenmedi. (p=0.209).Sonuç:Yaptığımızbu çalışmada üretra darlığını endoskopik cerrahisinde, lazerüretrotomi tekniğinin, coldknife üretrotomiye göre yüksek Qmax değerlerine ve daha düşüknüks oranına sahip olması nedeniyle daha başarılı bir cerrahiyöntem olduğu saptanmıştır. Sonuçların prospektif, randomizeçalışmalarla desteklenmesi gerekmektedir.
