Internal urethrotomy using sachse knife for managing urethral strictures

Urethral strictures secondary to trauma have been a frequent cause of obstruction in the male population residing in Saudi Arabia. This study of 59 patients presenting with urethral strictures covers a two-year period. Patients were asked to return for the initial follow-up one month after treatment and were asked about the force of their urine stream. They returned again after six months for a urethrogram; finally yearly follow-ups were commenced.     

Internal urethrotomy of urethral strictures in men under endoscopic control]

From November 1972 to October 1974 190 patients of the "Urologische Klinik der St?dt. Krankenanstalten Karlsruhe" with urethral strictures were treated by internal urethrotomy under endoscopic control with the modified urethrotome from Stortz/Germany. This is a report about short-time results (2-14 months) after treatment. The method is very simple and the effect is controlled by endoscopy. In the first 44 patients we used general or lumbal anaesthesia. In the last patients only local anaesthesia by Instillagel installation into the urethra was used. The short-time results were excellent in 66.8%. We believe that this method points out a new direction in the surgical treatment of urethral strictures.     

Internal urethrotomy, a modern method in the treatment of urethral strictures

The aim of this study was to evaluate the internal urethrotomy in the treatment of urethral strictures, by the retrospective analysis of 54 cases. The patients' age ranged between 18-92. 35 patients (64.8%) had iatrogenic strictures and 10 (18.5%) had traumatic ones. 35 patients presented with urinary infections before the procedure. Following internal urethrotomy, the medium hospital stay was 3.15 days. There were only 7 patients with postoperative fever and no death was recorded. The follow-up period was between 1-12 months with a medium of 9 months and only 2 patients required recurrent internal urethrotomy. Out of the 54 patients, 8 had recurrent urethral stricture disease and 6 of them had posttraumatic membranous urethral strictures. Optical internal urethrotomy appears to be the ideal therapeutic method of urethral strictures, because it has a low morbidity, it is safe to perform and the postoperative results are good. The hospitalization and the recovery periods are short, allowing a quick socio-professional reintegration. Most of the recurrencies occur with posttraumatic strictures.     

Visual internal urethrotomy in management or urethral strictures

Visual internal urethrotomy was used in the treatment of urethral strictures in 103 patients. The procedure was performed mostly under local anesthesia. Urethral catheter for forty-eight hours or urethral splinting for two weeks was used as complementary treatment in some cases. We obtained an overall success rate of 95.1 per cent.     

Internal urethrotomy under urethral anesthesia

A 64-year-old male patient with anterior urethral stricture was treated with internal urethrotomy after the instillation of 10 ml of 2% lidocaine into the urethra. This technique did not interfere with visual acuity and gave satisfactory analgesia for the patient.     

窥镜直视下尿道内切开术加电切术治疗尿道狭窄

目的：探讨尿道狭窄的有效治疗方法。方法：对1991—2000年收治的128例尿道狭窄患者的临床资料进行回顾性分析，并比较窥镜直视下尿道内切开术和直视下尿道内切开术加电切术的疗效。结果：作单纯直视下尿道内切开术56例，治愈29例(51．9％)。作窥镜直视下尿道内切开术加电切术72例，治愈63例(87．5％)。结论：窥镜直视下尿道内切开术加电切术的方法可明显提高尿道狭窄的疗效，减少其复发率。     

Direct vision internal urethrotomy in the treatment of urethral fistulas due to urethral strictures

Five cases of urethral fistula--three with single and two with multiple fistulous tracts--were treated by optical urethrotomy. All of the fistulas healed completely.     

The impact of optical urethrotomy on the management of urethral strictures

The introduction of optical urethrotomy by Sachse has reduced the need for urethroplasty: 261 urethroplasties were performed between 1964 and 1983, of which 87 were performed in one stage on patients who would today have undergone urethrotomy as the procedure of first choice. The results in this group are compared with those in 151 patients treated between 1978 and 1983 by 265 internal optical urethrotomies. At 5 years 50% of those treated by urethrotomy needed no further treatment, compared with 83% of those treated by urethroplasty. Nevertheless, the ease and safety of urethrotomy makes it the procedure of first choice, and urethoroplasty should be reserved either for cases where urethrotomy is unsuitable or where it has been tried on several occasions without success.     

Core-through optical internal urethrotomy in management of impassable traumatic posterior urethral strictures

During a 2 1/2-year period 10 patients with a traumatically obliterated posterior urethra underwent core-through optical internal urethrotomy 3 to 6 months after pelvic fracture. After 6 to 24 months of followup the peak urine flow rate was more than 15 ml. per second in 6 patients and 8 to 15 ml. per second in 2. Six patients were continent and 2 had transient stress urinary incontinence. Of the 10 patients 2 were failures because of peak urinary flow rates less than 8 ml. per second and/or urinary incontinence. Subsequently, 1 patient underwent successful scrotal flap urethroplasty. Core-through optical internal urethrotomy is an attractive alternative to urethroplasty when the impassable stricture is short.     

Buccal mucosa urethroplasty for the treatment of bulbar urethral strictures

PURPOSE: We report the results of urethroplasty with a free graft of buccal mucosa as a dorsal onlay for the treatment of bulbar urethral strictures. MATERIALS AND METHODS: Since June 1994, 30 patients with bulbar urethral strictures have been treated with buccal mucosa urethroplasty. Urethroplasty was performed with a free graft of buccal mucosa using a ventral onlay in the first 7 patients and a dorsal onlay in 23. Dorsal urethrotomy was performed with a Sachse urethrotome after the bulbar urethra was separated from the corpora. The buccal mucosa onlay was sutured to the urethra and corpora cavernosa to ensure a patent urethra. RESULTS: At 20-month followup (range 3 to 50) the success rate was 96% (29 of 30 patients). Urethral stricture recurred in only 1 of 7 patients in the ventral onlay and none of 23 in the dorsal onlay group. CONCLUSIONS: Preliminary results of urethroplasty for bulbar urethral strictures with a dorsal onlay graft of buccal mucosa are excellent. Longer followup is needed to evaluate definitive results.
