Vaginoplasty presents the main problem in male-to-female surgery. There are many operative techniques [1–3] that can be used, but none is ideal. Therefore, continual challenge exists in search for new and better solutions. We have published our contribution to operative technique in male-to-female surgery [4]. Afterwards we continuously improved th...

To report our experience of treating severe penile injuries with different causes and treatments, as penile trauma presents a difficult physical and psychological problem, and the type and extent of injury varies from mild to severe, sometimes even with total amputation.
We analysed retrospectively 43 patients (mean age 28 years, range 5-52 years)...
Metoidioplasty represents one of the variants of phalloplasty in female transsexuals. Its main characteristic is that it is a one-stage procedure. It involves lengthening and straightening of hypertrophied clitoris to create a neophallus, urethral lengthening to enable voiding while standing, and scrotal reconstruction with insertion of testicle pr...
Different tubular structures have been used to create cutaneous catheterizable continent urinary stomas. The most common complication is stomal stenosis on the cutaneous end of the tubes. We present a variant of stomal stenosis repair that uses a buccal mucosa graft.

Purpose
Total phalloplasty in children generates a great dilemma concerning indications as well as neophallic size. Evaluating long-term results of total phalloplasty using different flaps with poor results regarding penile size, we developed a technique using a latissimus dorsi free flap in children with micro or absent penis and difficult psychol...
Total phalloplasty is rarely performed in children due to the mutilation involved and the dilemma concerning neophallic size in children. We present a musculocutaneous latissimus dorsi free transfer flap for total phalloplasty in children with difficult psychological problems.
Total phalloplasty was performed in eight boys aged between 10 and 15 ye...

Bladder autoaugmentation is a procedure that includes detrusoromyotomy or detrusorectomy with an aim to release intact urothelium, which then prolapses and increases bladder capacity and compliance. Covering of the prolapsed urothelium usually is done by using deepithelialized pedicled colonic or gastric patch. The authors present their first exper...
Only sparse data are available on the blood supply of the hypospadiac prepuce. We investigated the development and course of the preputial blood vessels, and applied the results of this study to surgery for hypospadias.

This review will highlight recent advances in the field of penile reconstructive surgery in the paediatric and adult population. It is based on the work published during the year 2001. Besides the anatomical and histological studies of the penis, major contributions have been described in congenital and acquired penile anomalies. Also, a few new te...
To describe a technique for penile lengthening and the results achieved.
The penis is completely disassembled into its anatomical parts; the glans cap remains attached dorsally to the neurovascular bundle and ventrally to the urethra and corporal bodies. A space is created between glans cap and the tip of corpora cavernosa; this space is used to in...
To present an approach for treating Peyronie's disease, using the penile disassembly technique for reconstructive surgery.
From November 1996 to September 2000, 74 patients with Peyronie's disease were treated surgically. The penile disassembly technique was used in 46 of the patients (mean age 51 years, range 21-63). The indications were severe pe...
To describe and present the results of a one-stage vaginoplasty in male-to-female sex reassignment surgery.
The present technique is based on penile disassembly and the use of all penile components for vaginoplasty (except the corpora cavernosa). The neovagina consists of two parts; a long vascularized urethral flap and a pedicled island tube skin...
Megaureter represents the ideal tissue for bladder augmentation but to date ureterocystoplasty has been used only in select cases. We demonstrate that ureterocystoplasty can be used more frequently by dividing the megaureter and using its distal part for bladder augmentation and proximal part for reimplantation into the bladder. This technique can...

We present 2 variants of the penile disassembly technique for epispadias repair that refine some details of the Mitchell technique. In some cases the urethral plate retracts and shortens, and there may be poor vascularization at the most distal portion. In addition, when the neurovascular bundles of the separated hemicorporeal glanular bodies are i...
We report our experiences with penile disassembly technique in the treatment of severe hypospadias. During a period from November 1995 to December 1997 the technique was applied to 102 patients, aged from 9 months to 32 years. The principle of the technique involves separation of the penis into its component parts: glans cap with neurovascular bund...
Techniques for penile straightening generate the serious dilemma of which is most appropriate. We created and describe our penile disassembly technique to avoid penile shortening in curvature repair.
From November 1995 to March 1997 we performed our penile disassembly technique in 87 patients 12 months to 47 years old (mean age 4.5 years). Indicati...
To report experience and results with penile disassembly in hypospadias repair.
From November 1995 to May 1997 penile disassembly was used in 92 patients aged from 9 months to 32 years. The indications for operation were hypospadias with severe penile curvature (especially with curvature in the distal third of the corpora cavernosa), chordee withou...
The field of hypospadiology remains full of challenges in the search for new and better solutions. In recent years, our concept has involved being very radical in penile reconstructive surgery, using an aggressive approach. The penile disassembly technique, either complete or incomplete, is used successfully in epispadias repair. We began using pen...
We report our efforts to create an ideal continent urinary catheterizable stoma.
Our approach includes the creation of a continent stoma using a preputial penile island skin flap in male patients and a preputial clitoral island skin flap in female patients. The flaps are transposed suprapubically, tubularized and implanted in a nonrefluxing manner...
Despite the progress made in understanding the factors regulating sexual differentiation, infants born with ambiguous genitalia face significant problems. The authors reviewed a group of 84 children with ambiguous genitalia managed surgically between 1986 and 1993. The most frequent condition was male pseudohermaphroditism (PM) (58%); 31% had femal...
An operative procedure for phalloplasty is reported that uses an extended pedicle island groin flap. Forming a combined groin and lower abdominal flap based on the superficial iliac and epigastric vessels is the main characteristic of this technique. The flap consists of 3 parts: 1) the lateral narrow hairless part for the neourethra, 2) the medial...
A variant of the onlay island flap urethroplasty in severe hypospadias repair is described. The principles of technique are: mobilizing of urethral plate, without dividing it, in order to release chordee; creation of pedicle island flap on the dorsal penile skin, with redundant vascularized tissue, which is transposed to the ventral side of penis b...
From 1987 to 1992, 128 predominantly male patients 15 days to 19 years old (mean age 22 months) with a total of 167 megaureters underwent surgery for obstruction and/or reflux and symptomatic recurrent urinary infections. The technique consists of creating 2 holes through a muscle up to the mucosa by the detrusor splitting maneuver on the lateral b...

A 1-stage surgical repair of penoscrotal transposition with hypospadias is described. The basic principles are correction of hypospadias with the best vascularized island penile skin flap used for a new urethra and 2 vascularized sliding skin flaps used for reconstruction of the penile skin, and transposition of the penis to the suprascrotal positi...
Das Grundproblem in der chirurgischen Behandlung der Epispadien stellt die Penislänge dar. Bei dieser Mißbildung ist nämlich der Penis sehr kurz, mit ausgeprägter dorsaler Krümmung. Dies alles wird durch die Divergenz der Schwellkörper, ihre Beziehung zum Schambein, das Vorhandensein außerordentlich kurzer Harnröhre oder durch die Veränderungen der...
Hypospadia sine Hypospadia stellt ein klinisches Syndrom dar, das drei morphologische Einheiten einbezieht, deren Eigenschaftbezeichnung ist die Peniskrümmung zu verursachen. Diese Einheiten sind: die Hautchorda, die fibröse Chorda und „congenital short Urethra“.
