“…Nd:YAG, KTP, argon, excimer, diode lasers, and finally Ho:YAG laser have been used in endoscopic treatment of urethral stricture disease [6e16]. Bloiso et al [9] documented 67% recurrence rate with Nd:YAG laser after 1-year follow-up. However, Perkash [5] and others reported a 93% success over a follow-up of 28 months by using contact chisel-crystal fired Nd:YAG laser.…”

In this prospective randomized clinical trial, we aimed to evaluate the safety and efficacy of endourethrotomy with holmium:yttrium-aluminium-garnet (HO:YAG) laser and compare the outcomes with the conventional cold-knife urethrotomy. Fifty-one male patients with single, iatrogenic, annular strictures of the urethra were randomly divided into two groups; 21 patients who underwent direct-vision endoscopic urethrotomy with Ho:YAG laser (15 W; 1,200-1,400 mJ; 8-12 Hz) at 12 o'clock position (laser group) and 30 patients who underwent direct-vision endoscopic urethrotomy with cold-knife incision at 12 o'clock position (cold-knife group). The results obtained were analyzed and compared at 3 months, 6 months, 9 months, and 12 months postoperatively by clinical evaluation, uroflowmetry, and retrograde urethrographies. Variables were compared among groups using Fisher's exact and Mann Whitney U tests. There were no differences between two groups in terms of patient age, preoperative Qmax value, stricture location, and length. Operative time was shorter in laser group (16.4 ± 8.04 minutes) when compared with cold-knife group (23.8 ± 5.47 minutes) (p<0.001). Recurrence-free rate at 3 months was similar between two groups (p=0.122). However, recurrence-free rates at 6 months, 9 months, and 12 months were significantly higher in laser group when compared with cold-knife group (p values were 0.045, 0.027, and 0.04, respectively). No intra- or postoperative complications were encountered. Use of Ho:YAG laser in the management of urethral stricture disease is a safe and effective method. In addition, it provides shorter operative time and lower recurrence rate when compared with the conventional technique.

Prostatectomy is one of the main causes of surgery in aging male population. Besides traditional techniques, novel minimally invasive approaches may also end up with certain complications following prostate surgery. Transurethral procedures may cause iatrogenic urethral trauma. Factors that may influence the development of iatrogenic endoscopic urethral strictures include "electrical dispersion" generated by unipolar current and the "diameter of the instruments" used. Those complications not only bother quality of life of the patients but also may cause various adjunctive procedures with an economical impact.Urethral stricture is the abnormal narrowing of any segment of the urethra surrounded by corpus spongiosum. It specifically means varying degrees of spongiofibrosis that refers to scarring of the corpus spongiosum (1). Any inflammation of the urethra can result in scarring that can lead to a stricture or a narrowing of the urethra. Besides prostate surgery, trauma, infections, tumors or any other cause of scarring may trigger urethral stricture (2). A recent metaanalysis including 732 patients showed that idiopathic and iatrogenic etiologies were by far the most common, accounting for 33% and 33% of all cases, respectively. Inflammatory and posttraumatic etiologies were found in only 15% and 19% of patients, respectively (3).Here, we tried to review the incidence and the basic risk factors that cause urethral stricture following prostate surgery. ÖZÜretral striktür enflamasyona bağlı olarak skarlaşma sonrası üretradaki daralmadır. Elli yaş üzeri erkeklerde benign ve malign hastalıklara bağlı olarak yapılan prostatektomiler oldukça yaygın olarak uygulanmaktadır. Prostatın transüretral rezeksiyonu sonrası farklı serilerde %19'a kadar çıkan oranlarda üretral darlık ve mesane boynu kontraksiyonu görülmektedir. Lazer prostatektomi sonrası üretral darlık prostatın transüretral rezeksiyonuna oranla daha az olarak görülmektedir, yaklaşık olarak %3,6 oranındadır. Açık prostatektomi en eski yöntem olmasına rağmen büyük prostat boyutlu hastalarda oldukça mantıklı bir alternatiftir. Açık prostatektomi sonrası yaklaşık olarak %1,9-4,8 oranında darlık bildirilmiştir. Radikal prostatektomi (RP) lokalize prostat kanseri tedavisinde bütün dünyada en yaygın olarak uygulanan yöntemdir. RP sonrası anastomoz seviyesinde mesane boynu kontraksiyonu olması iyi bilinen bir komplikasyondur ve yaklaşık olarak hastaların %0,4-32'sinde görülmektedir. Darlık büyük oranda endoskopik yöntemlerle tedavi edilmektedir, nadiren komplike olgularda bukkal mukoza greftli üretroplasti gerekebilmektedir. Anahtar Kelimeler: Üretral darlık, prostat cerrahisi, transüretral rezeksiyon, açık prostatektomi, radikal prostatektomi ABSTRACTUrethral stricture is narrowing of the urethra due to inflammation that results in scarring. Prostatectomies for benign and malign prostatic diseases are common surgical procedures among men mainly after their fifties.

“…Nevertheless, good results have been obtained in only 50-60% of cases [2][3][4][5], because multiple variables are involved before a successful outcome is achieved: (a) whether the treat ment is primary or secondary [3]; (b) the etiology of the stricture [6,7]; (c) the location of the stricture [6,8]; (d) its length [8,9]; (e) the number if strictures [6,8], and finally the duration of follow-up [8,10], Based upon the physical principles fo the laser beam [11,12] which have been confirmed experimentally [11], the Nd-YAG laser has been used since 1979 [13] for the treatment of urethral strictures in an attempt to decrease the number of recurrent posturethrotomy strictures. The results obtained by the different series in the literature are not very encouraging, with an incidence of recurrent strictures approaching 40-60% [14][15][16][17]. Nevertheless, patient selection and duration of follow-up differ be tween authors.…”
