Refinements in buccal mucosal graft urethroplasty for hypospadias repair
1998
We evaluated our experience with buccal mucosa in urethral reconstruction for complex hypospadias repair in a total of 62 children operated on at our institution since 1990 at a mean follow-up of 23 months. After the graft had been taken from the lower lip, with possible extension to the inner cheek, complete thinning of the graft was performed. The graft was then sutured in an onlay fashion to the urethral plate, and suprapubic urinary diversion was carried out for 3 weeks. The overall complication rate in this rather complex series of patients, including 26 "hypospadias cripples," was 13%; the complications involved 4 fistulas, 3 cases of graft necrosis, and only 1 meatal stenosis during …
Anal endosonographic evaluation after closed lateral subcutaneous sphincterotomy
1998
PURPOSE: The present study was undertaken to evaluate anal endosonographic results of the transverse and longitudinal extent of internal anal sphincter division after closed lateral subcutaneous sphincterotomy and its relationship to outcome with respect to anal fissure recurrence and postoperative anal incontinence. METHODS: Ten patients selected for symptomatic anal fissure recurrence (mean follow-up, 10.9 months) and 41 asymptomatic control patients (mean follow-up, 15.5 months) were reviewed by anal endosonography after closed lateral subcutaneous sphincterotomy. Clinical evaluation was focused on anal fissure recurrence and postoperative anal incontinence. The anal endosonographic stud…
Oral complications after lingual mucosal graft harvest for urethroplasty
2007
Background: The aim of this study was to assess the complications at donor site after lingual mucosal graft harvesting for urethroplasty. Methods: From March 2006 to December 2006, 30 patients of anterior urethral stricture underwent lingual mucosal graft urethroplasty. The site of the harvest graft was lateral mucosal lining of the tongue. Donor site complications, that is, pain, slurring of speech, pain during speech, salivatory changes and difficulty in protrusion of tongue were noted. Results: The mean (range) age of patients was 36.2 years (22–52 years). The mean (range) stricture length was 8.4 cm (4.8–16 cm) and graft length was 8.5 cm (4.2–16.2 cm). Mean duration of follow up was…
Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.
2005
PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play in important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemaorrhoidectomy in reducing the maximum testing pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward ill all patients un…
The Buccal Mucosal Graft For Urethral Reconstruction: A Preliminary Report
1992
Autologous buccal mucosa as a substitute for urethral epithelium was studied in 2 dogs and used in 6 patients with difficult urethral reconstruction problems. The indications for an operation in these patients were failed hypospadias repairs with limited skin in 3, severe structure disease after hypospadias repair in 1, a short urethra in 1 and epispadias in 1. Three urethral fistulas and 1 meatal stenosis occurred in 3 patients. No urethral stricture or diverticulum was noted, and the final outcome was good functionally and cosmetically in all patients. This technique is useful for urethral reconstruction when local skin is not available.
Successful treatment of condylomata acuminata at the urethral meatus with high-dose ingenol mebutate gel: Report of two cases
2019
Condylomata acuminata (CA), or anogenital warts, is the most common sexually transmitted infection. Treatments for CA generally have suboptimal recurrence rates, which results in a need for repeated treatments and adds to the already negative impact on the patients’ quality of life. CA can present at the urethral meatus, which is a particularly challenging anatomic location from a therapeutic perspective. We report two cases of CA at the urethral meatus successfully treated with topical application of high-dose ingenol mebutate gel.
Tunica vaginalis Free Grafts for Closure of Urethrocutaneous Fistulas
1990
In 32 patients a tunica vaginalis free graft was used for closure of urethrocutaneous fistulas (n = 26) or complicated hypospadias repair (n = 6). All patients had at least one operation (average 3.9) for urethral reconstruction prior to this procedure. 12 patients had recurrent fistulas (average 2.2). The technique proved to be very successful. Only 2 patients had to undergo subsequent reoperation for recurrent fistulas. The use of a free tunica vaginalis graft interposed between skin and urethra is our method of choice in the repair of recurrent or complicated urethrocutaneous fistulas.
The ideal lateral internal sphincterotomy: clinical and endosonographic evaluation following open and closed internal anal sphincterotomy
2009
To evaluate the relationship between extent of internal sphincter division following open and closed sphincterotomy, as assessed by anal endosonography, with fissure persistence/recurrence and faecal incontinence.A total of 140 consecutive patients undergoing lateral internal sphincterotomy (LIS) for idiopathic chronic anal fissure were prospectively studied. Preoperative clinical assessment was performed together with a postoperative clinical and endosonographic examination. Three zones of the internal sphincter, identifiable by endosonography, were used to describe the uppermost extent of LIS. Primary end-points were fissure persistence/recurrence and faecal incontinence.A total of 140 pa…
Anorectal function and morphology in patients with sporadic proctalgia fugax
1996
PURPOSE: The pathophysiology of sporadic proctalgia fugax remains unknown. This study investigates whether patients with this syndrome exhibit alterations in anal function and morphology. METHODS: Eighteen patients with sporadic proctalgia fugax and 18 sex-matched and age-matched healthy controls were studied. Manometric studies investigated anal resting and squeeze pressures, the rectoanal inhibitory reflex, rectal compliance, and smooth muscle response to edrophonium chloride administration. External and internal sphincter thickness was measured endosonographically. RESULTS: Patients had slightly higher (P=0.0291) anal resting pressures (65.5±11.4 mmHg) than controls (56±9.9 mmHg). Howeve…
Randomized clinical trial of botulinum toxin injection for pain relief in patients with thrombosed external haemorrhoids
2008
Abstract Background Thrombosed external haemorrhoids are one of the most frequent anorectal emergencies. They are associated with swelling and intense pain. Internal sphincter hypertonicity plays a role in the aetiology of the pain. This study evaluated the efficacy and safety of an intrasphincteric injection of botulinum toxin for pain relief in patients with thrombosed external haemorrhoids. Methods Thirty patients with thrombosed external haemorrhoids who refused surgical operation were randomized into two groups. Patients received an intrasphincteric injection of either 0·6 ml saline or 0·6 ml of a solution containing 30 units botulinum toxin. Anorectal manometry was performed before tr…
