Use of the Otis urethrotome in the treatment of urethral strictures and congenital urethral stenoses.

Internal urethrotomy using the Otis urethrotome is described in detail. Performing this procedure in 23 patients with urethral strictures, no further dilatations of the urethra were necessary in approximately 60%. If internal urethrotomy, which offers the advantages of having a very low rate of complications and which may be repeated, proves unsuccessful, a urethroplasty can still be carried out. As a preliminary procedure to transurethral resection of the prostate by cold punch technique, internal urethrotomy appears to be of great value in preventing urethral strictures - as demonstrated by follow-up studies in 351 patients.

Treatment of posterior urethral strictures with a titanium urethral stent.

A total of 5 patients with recurrent posterior urethral strictures underwent endoscopic placement of an expandable endourethral stent made of titanium. Patient age ranged from 17 to 66 years (mean age 42.6 years). Followup ranged from 13 to 20 months (mean 14.1 months). Of the patients 4 presently have unobstructed voiding with no incontinence. To date no side effects have been directly related to the stents and no incrustations or calculi have formed. Our preliminary study supports the use of titanium urethral stents as an alternative form of treatment for selected urethral strictures.

Surgical management of urethral strictures based on etiology. Where do urethral stents fit in?

Recent studies in the urologic literature indicate a renewed interest in the management of urethral stricture disease. Specifically, urologists are now treating all types of urethral strictures regardless of location, etiology, or extent with methods other than primary urethroplasty or direct vision internal urethrotomy (DVIU), i.e., balloon dilation or urethral stenting. To see which patients might best be managed by these new modalities, we reviewed our experience with urethral strictures at LAC-USC Medical Center.

[Urethral stricture].

The incidence of urethral stricture has increased since the introduction of gonorrhoea to Europe in the 15th century. Nowadays, transurethral instrumentations and catheterisations are responsible for the majority of the urethral strictures. The mechanism is inflammatory or traumatic lesion of the urethral epithelium causing extravasation of urine and fibrosis. The symptoms often suggest to infravesical obstruction. The diagnosis is made from the patient's history in combination with flowmetry, ante- and/or retrograde urethrography, external ultrasound examination or urethral calibration and is verified at urethroscopy. Dilatation is relatively simple but seldom curative and carries a considerable morbidity. Urethrotomy is very common but also hampered with a high rate of recurrence. A technique where urethrotomy is followed by intermittent self-catheterisation or implantation of a selfexpanding wire netting seems promising but needs further investigation. Reconstructive operations in form of a free or pedicled skin island patch, skin tube graft, endourethral free split skin graft, multistaged urethroplasty, meatoplasty and excision of prostatomebraneous stricture are followed by cure in 50-95% of the cases.

[Retrograde balloon catheter dilatation of urethral stenosis--experience in benign prostatic hypertrophy and postoperative urethral stricture].

Retrograde transurethral balloon dilatation of urethral stenosis was performed in five patients: four patients with benign prostatic hypertrophy and one with urethral stricture following open prostatectomy. Significant resolution of symptoms of dysuria was seen in four patients throughout the follow-up period of 12 to 18 months. A balloon diameter of 25 mm was considered to be necessary for prostatic hypertrophy. The unsatisfactory result in one patient with prostatic hypertrophy was believed to be caused by incomplete dilation due to a small balloon diameter. Mild transient hematuria was seen in all cases. Only one patient with postoperative urethral stricture complained of pain during balloon inflation, while other patients with prostatic hypertrophy did not complain of any apparent pain. We conclude that this technique is a safe and effective method of treatment for prostatic hypertrophy and other urethral strictures.

Balloon dilatation for entire urethral stricture.

Two patients with entire urethral stricture were treated with balloon dilatation of the whole urethra using a torpedo-type dilatation balloon with satisfactory results. Postdilatation urethrograms revealed that the lumen of the urethra was of satisfactory width in both cases, and the patients are now voiding normally. There has been no complication requiring therapy. These successful results suggest that this technique is a good alternative treatment for entire urethral stricture, and can replace conventional dilatation.

[Treatment results in urethral strictures].

A total of 231 patients with urethral strictures were treated. The disease resulted from trauma, adenomectomy, chronic urethritis, prostatic sclerosis in 92, 72, 51 and 16 patients, respectively. Fifty-one patients underwent conservative treatment which involved bougienage, resolving and anti-inflammatory agents. 38 of them responded, 13 nonresponders were operated on. 72 patients were subjected to partial urethral tunneling according to an original technique which brought success in 90% of the cases. Out of 92 traumatic urethral strictures 88 were cured after end-to-end plastic reconstruction. It is believed that urethral strictures should be managed individually basing on the stricture cause, location, length, severity, complications.

Urethral strictures in boys.

Our experience with urethral strictures in boys during a 15-year period confirms the findings of others that the most common etiology is iatrogenic. Traumatic and inflammatory strictures are rare. The congenital stricture differs fundamentally from acquired types of urethral strictures and would be termed more appropriately congenital urethral membrane. Urethral dilation and/or urethrotomy was unsuccessful in 47% of our patients, leading to secondary formation of a new stricture in 2 instances. However, urethroplasty was successful in 83% of our cases and seems to be indicated when 2 or more dilations are required.

Effect of catheter material on the incidence of urethral strictures.

The aetiology of urethral strictures in patients catheterised for short periods at the time of surgery is the subject of some debate. The occurrence of epidemics of strictures associated with certain batches of latex catheters, and the demonstrable in vitro cytotoxicity of latex in general, have supported the suggestion that catheter material (and in particular latex) has an important role. We have looked retrospectively at 299 patients undergoing transurethral resection of the prostate gland by 1 urologist, 135 of whom had a latex catheter and 164 a plastic one; 19 patients developed strictures over the next 12 months with no proven difference attributable to the catheter material. The study provides no evidence that the short-term use of latex catheters is associated with stricture formation.

Turner-Warwick urethroplasty and urethral stricture. Results in 60 patients.

Sixty patients with urethral strictures at the bulbous and membranous levels were treated with Turner-Warwick urethroplasty. Initially, there were significant difficulties with restenosis of either the proximal or distal st-ma following the first-stage urethroplasty. Use of nitrofurazone-hydrocortisone (Furacin-Hc) urethral suppositories practically eliminated recurrent stomal stenosis after the first stage. Several additional modifications were made in the original technique; these included placement of urethral sutures prior to scrotal mobilization and abandonment of the suprapublic cystotomy for frainage at the second stage of the procedure. These modifications increased the chances of achieving a successful result while facilitating the actual surgery and improving the patients' comfort. The over-all success rate was approximately 90 per cent. Patients with urethral stricture surgery subsequent to prostatectomy had problems with urinary control, but not so if prostatectomy was done after the first stage of urethroplasty. It appears that the Turner-Warwick urethroplasty is good one, and predictably good results can be expected on selected patients with urethral strictures.

Transurethral resection in children with urethral stricture and occlusion.

Technical considerations of urethral surgery in children are critical because of the small size and delicacy of their urethra. From 1984 to 1989, 10 children with serious traumatic urethral stricture (5 cases) and occlusion (5) were treated satisfactorily by an improved transurethral resection (TUR). The age of the children ranged from 4 to 14 years. The TUR technique, curative effects and prevention of urethral stricture are discussed.

A comparative study of electrosurgical vs. cold urethrotomy in the treatment of urethral strictures.

Thirty-one patients with urethral stricture were subjected to internal urethrotomy under visual control. The patients were divided into two groups according to the surgical procedure: electrosurgical or cold resection. A modification of the Sachse knife was introduced in order to permit its use with the American Cystoscope Makers Inc. instruments. The success rate with cold resection was 81.81% and with the electrosurgical procedure 40%. Internal urethrotomy with cold resection is a simple and harmless operation, being a first choice in the treatment of urethral stricture.

Transpubic urethroplasty for membranous urethral strictures.

Six patients with traumatic membranous urethral strictures have undergone urethroplasty utilizing the traspubic approach with resection of a wedge of the symphysis pubis. Three patients are free of stricture, 2 required urethral dilatation in the early postoperative period only, and 1 patient requires dilation every three months. Four patients are completely continent of urine, 1 has mild stress incontinence, and 1 is incontinent because of a neurogenic bladder. This approach provides excellent exposure with minimal morbidity and allows an easy under-vision anastomosis.

Urethral stricture in children: treatment by urethroplasty with bladder mucosa graft.

Urethral strictures in children, which are not frequent, often require urethroplasty when dilations and/ or urethrotomies have failed. A bladder mucosa graft was used successfully for urethral reconstruction to treat posterior hypospadias. We describe our experience with a bladder mucosa graft during urethroplasty for acquired urethral strictures in 8 children. Urethral strictures secondary to the treatment of hypospadias were excluded. Bladder mucosa was used successfully as an onlay or patch graft urethroplasty in 7 patients. One patient had a tubularized graft with secondary stenosis treated successfully by dilation.

[Urethral stricture in Greenland].

In a retrospective survey, the 46 patients treated for urethral stricture at Dronning Ingrids Hospital, Nuuk, (the main hospital in Greenland) during the four year period August 1987-August 1991 are investigated, and the consequences of not treating urethral stricture are illustrated by a case. The patients are middleaged and older men generally with long and multiple strictures close to the sphincter. Gonorrhoea is the common cause of the stricture. The patients have obstructive symptoms, urinary infections and haematuria. Furthermore, nearly 1/4 of the patients have complications in the form of scrotal and perineal abscesses, and reduced renalfunction and rapidly lethal disease because of sepsis are seen. The urethral strictures tend to recur after treatment. Urethral stricture disease is undoubtedly underestimated in Greenland, and the investigation stresses this serious complication of venereal disease.

The anatomy of the urethral stricture.

A post-mortem study of the urethral anatomy following gonorrhoea is presented. The different specimens examined demonstrated lesions ranging from microscopic submucosal scars to fully developed urethral strictures. In every specimen extensive squamous metaplasia of the surface epithelium was present. It is postulated that overstretching of this unsupported squamous epithelium during voiding causes microscopic epithelial tears and that the accumulation of the subsequent microscopic scars leads to the formation of a urethral stricture. Bacterial infection does not seem to play any part in the genesis of the stricture.
