Peyronie disease: surgical treatment with muscular aponeurosis.

A new method for surgical correction of Peyronie disease by grafting autologous muscular aponeurosis was tried in 4 patients. Early results were encouraging, with disappearance of penile curvature and of pain on erection. The urologist can perform the operation without the assistance a plastic surgeon must usually give when dermal grafts are used.

Splenic rupture and abscess after extracorporeal shock wave lithotripsy.

Extracorporeal shock wave lithotripsy (ESWL) is the first choice for the treatment of most urinary stones. Complications of ESWL can be separated into two groups: those related to the administration of the shock waves and those related to fragmentation and elimination of the stone's particles. We report a rare case of splenic trauma followed by abscess after ESWL.

Comparison of videolaparoscopic versus open surgery for benign renal diseases in children.

INTRODUCTION: Laparoscopic nephrectomy in children has become a reasonable alternative to open nephrectomy and has replaced open surgery for many kidney diseases. The aim of our study is to evaluate transperitoneal videolaparoscopic procedures in benign renal disease compared with the open surgical approach. PATIENTS AND METHODS: 34 children aged between 17 days and 15 years (mean, 6.14 years) were divided into two nephrectomy groups. The first underwent transperitoneal videolaparoscopic nephrectomy and was composed of 21 patients (12 female and 9 male) aged between 2 months and 15 years (mean, 7.42 years). The second group underwent open nephrectomy and was composed of 13 patients (6 female and 7 male) aged between 17 days and 11 years (mean, 3.91 years). The groups were compared for time of anaesthesia, operating time, length of hospital stay, postoperative pain and time to restore oral intake. Short and long term complications were also evaluated. Statistical analysis was performed by a Student's t test, with a p value < 0.05 being considered significant. The study was approved beforehand by the Scientific Ethics Committee in our institution. RESULTS: Statistically significant differences were observed only for the length of hospital stay. No cases in the laparoscopic group were converted into open surgery. There were no immediate or late complications. Blood loss was negligible and so it was not necessary to administer any transfusions. CONCLUSIONS: In our experience, transperitoneal videolaparoscopic nephrectomy has similar results to those of open nephrectomy, except for hospitalisation times.

Modified meatal advancement and glanuloplasty repair of distal hypospadias.

Meatal advancement with glanuloplasty is indicated in cases of distal hypospadias. The principles of this operation are safe. Incorporation of urethroplasty with meatal advancement and glanuloplasty enables treatment of the more severe cases of distal hypospadias. We have used this modified operative technique in 10 boys with only 1 complication, which probably was related to the wrong choice of urinary diversion.

Incontinent epispadias: surgical treatment of 38 cases.

We review 38 cases of surgically corrected incontinent epispadias with a followup of 5 months to 18 years. In 20 cases the Leadbetter, in 8 the Tanagho and in 8 the Young-Dees techniques of bladder neck reconstruction were used. Of 3 patients with minimal (15 to 25 ml.) bladder capacity the Arap procedure was performed in 1, while small constriction of the bladder neck to improve the bladder capacity and compliance was done in 2. In 1 of the latter patients a 60 ml. capacity was achieved and a secondary Leadbetter operation provided an excellent result. Continence was attained after the initial operation in 18 patients, followup is too short to determine the result in 3 and 15 did not acquire urinary control. Revision of the bladder neck plasty was performed in 11 patients, which resulted in continence in 4 and partial continence in 2. Among 34 patients with an adequate followup 22 (73.3 per cent) are continent and 8 (26.4 per cent) are incontinent. The results were similar with the 3 techniques.

Genital trauma due to animal bites.

PURPOSE: Animal bites to the external genitalia are rare. We retrospectively evaluated our experience with treating genital trauma caused by animal attacks. MATERIALS AND METHODS: We studied the medical records of 10 patients treated in the surgical emergency department at our hospital who presented with genital injury caused by an animal bite from 1983 to 1999. Special attention was given to the severity of injury, surgical treatment, antibiotic prophylaxis and outcome. RESULTS: Of the 2 men and 8 boys 8 were attacked by dogs, 1 by a horse and 1 by a donkey, respectively. In all cases initial local treatment involved débridement and copious wound irrigation with saline and povidone-iodine solution. Five patients who presented with minimal or no skin loss underwent primary skin closure, including 2 in whom urethral lacerations were surgically repaired. There was moderate to extensive tissue loss in 5 patients, including degloving penile injury in 2, traumatic spermatic cord amputation in 1, complete penile and scrotal avulsion in a 5-month-old infant, and partial penectomy in 1. Reconstructive procedures provided satisfactory cosmetic and functional results in 8 cases. Antibiotic prophylaxis was administered in all patients and no infectious complications developed. CONCLUSIONS: Animal bite is a rare but potentially severe cause of genital trauma and children are the most common victims. Morbidity is directly associated with the severity of the initial wound. Because patients tend to seek medical care promptly, infectious complications are unusual. Management involves irrigation, débridement, antibiotic prophylaxis, and tetanus and rabies immunization as appropriate as well as primary wound closure or surgical reconstruction. Good functional and cosmetic results are possible in the majority of cases.

[Persistence of Muller's ducts in the male. A family observation (author's transl)]. / Syndrome de persistance des canaux mullériens. Une observation familiale.

The authors report two cases (in brothers) of the persistence of Muller's ducts (uterus and uterine tubes), whilst both individuals led a normal though infertile sex life. They presented with a bilateral inguinal hernia and a cryptorchidism. The precise diagnosis was made at surgery in the first, whilst the family history led to the diagnosis in the second. Both underwent bilateral orchidopexy, and hysterectomy with excision of the uterine tubes. The caryotypes were normal. Of anatomical interest was the fact that both had vas deferens included within the uterine wall but the there was no continuity between the epididymes and the testes. The latter contained seminiferous ducts, Sertoli cells and spermatogonia but no spermatocyte nor spermatozoa. On the basis of these cases, the authors emphasise their demonstrative nature: the presence of testes resulted by the secretion of testosterone in the induction of normal external genitalia whilst the absence of factor inhibiting Mullers ducts (or tissue resistance to this factor) resulted in the development of the uterine tubes and uterus.

Nonrefluxing colonic conduit: efficiency and complications of ureterocolic anastomosis.

The efficiency of and complications in 65 cases of colonic conduit have been studied (64 cases of bladder exstrophy and 1 case of cloacal exstrophy). For the ureterocolic reimplantation, we employed the Leadbetter technique and a modified kelalis technique. The results after 1-12 years in 128 renoureteral units showed 28 complications (21 obstruction and 7 refluxing units). Other types of complications have been observed and reported in this work. The high incidence of obstruction was probably due to the long submucous tunnel in the ureterocolic reimplantation. We believe that the sigmoidal conduit is an adequate method for temporary or permanent diversion.

Ureterocele of the lower pole ureter and an ectopic upper pole ureter in a duplex system.

We report an unusual case of a ureterocele in a duplex system, which was associated with an ectopic (vulval) upper moiety ureter. This is the second case reported in the literature of a ureterocele arising from the lower pole ureter. Surgical treatment consisted of removal of the upper segment of the kidney and its ureter. The ureterocele was excised and the lower pole ureter was reimplanted in the bladder. At followup 14 years postoperatively the patient was cured and free of urinary infection.

Pheochromocytoma treated by laparoscopic surgery.

OBJECTIVE: To evaluate the results of the laparoscopic technique in the treatment of adrenal pheochromocytoma. METHOD: Ten patients, 7 men and 3 women, between 10 and 67 years of age (mean 48) with pheochromocytoma underwent transperitoneal laparoscopic adrenalectomy and were evaluated retrospectively, based on clinical, laboratory, and pathological diagnosis. In all cases there was a solid unilateral adrenal tumor, 5 on the left side and 5 on the right side, whose greater diameter varied from 7 to 80 mm (mean 32). Nine of the 10 patients were chronically hypertensive or had already had hypertensive crises. One patient was normotensive, but presented metabolic alterations suggestive of adrenergic hyperfunction. RESULTS: No deaths occurred in this series. There were two (20%) conversions to open surgery, one due to venous bleeding and one due to the difficulty of dissection behind the vena cava in a patient presenting a partially retro-caval tumor. Surgical time in the 8 non-converted cases ranged from 70 to 215 minutes (mean 136). One patient (10%) received blood transfusion, and another (10%) presented two complications - acute renal failure and a subcutaneous infection. Both had been converted to open surgery. None of the non-converted cases was transfused or presented complications. Hospital discharge occurred between the 2nd and 11th post-operative day (mean 3). The pathological exam of the surgical specimens confirmed the diagnoses of pheochromocytoma in all 10 cases, one of them associated with an aldosterone-producing cortical tumor. CONCLUSIONS: Laparoscopic adrenalectomy for selected patients presenting pheochromocytoma is feasible and provides good results.

Laparoscopic treatment of retroperitoneal fibrosis: report of two cases and review of the literature.

OBJECTIVES: We present the results of treatment by laparoscopy of two patients with retroperitoneal fibrosis and review the literature since 1992, when the first case of this disease that was treated using laparoscopy was published. We also discuss the contemporary alternatives of clinical treatment with corticosteroids and tamoxifen. CASE REPORT: Two female patients, one with idiopathic retroperitoneal fibrosis, and other with retroperitoneal fibrosis associated with Riedel's thyroiditis, were treated using laparoscopic surgery. Both cases had bilateral pelvic ureteral obstruction and were treated using the same technique: transperitoneal laparoscopy, medial mobilization of both colons, liberation of both ureters from the fibrosis, and intraperitonealisation of the ureters. Double-J catheters were inserted before the operations and removed 3 weeks after the procedures. The first patient underwent intraperitonealisation of both ureters in a single procedure. The other had 2 different surgical procedures because of technical difficulties during the first operation. Both patients were followed for more than 1 year and recovered completely from the renal insufficiency. One of them still has occasional vague lumbar pain. There were no abnormalities in the intravenous pyelography in either case. CONCLUSIONS: Surgical correction of retroperitoneal fibrosis, when indicated, should be attempted using laparoscopy. If possible, bilateral ureterolysis and intraperitonealisation of both ureters should be performed in the same operation.

Synchronous bilateral carcinoma of the adrenal gland: 2 case reports.

The existence of synchronous bilateral adrenal masses is an uncommon condition except in the relatively more frequent cases of pheochromocytoma or metastatic tumors. Two cases of synchronous nonfunctioning bilateral adrenal cortex carcinoma, removed during the same operation, are described. The patients currently are receiving hormonal supplementation, and were well 16 and 12 months postoperatively.

Comparación entre la cirugía videolaparoscópica y la cirugía abierta para las enfermedades renales benignas en el niño / Comparison of videolaparoscopic versus open surgery for benign renal diseases in Children

Introducción: La nefrectomía laparoscópica en niños se ha convertido en una alternativa razonable a la nefrectomía abierta y ha sustituido a la cirugía abierta en muchas enfermedades renales. El objetivo de nuestro estudio es evaluar los procedimientos videolaparoscópicos transperitoneales en las enfermedades renales benignas en comparación con el abordaje quirúrgico abierto. Pacientes y método: 34 niños de edades comprendidas entre los 17 días y los 15 años (media, 6, 14 años) fueron divididos en dos grupos de nefrectomía; el primero fue sometido a nefrectomía videolaparoscópica transperitoneal y estaba compuesto por 21 pacientes (12 mujeres y 9 varones) con edades comprendidas entre los 2 meses y los 15 años (media, 7, 42 años). El segundo grupo fue sometido a nefrectomía abierta y estaba compuesto por 13 pacientes (6 mujeres y 7 varones) con edades comprendidas entre los 17 días y los 11 años (media, 3,91 años). Los grupos se compararon respecto al tiempo de anestesia, el tiempo operatorio, la duración de la estancia hospitalaria, el dolor postoperatorio y el tiempo de reinstauración de la ingesta oral. También se evaluaron las complicaciones acorto y largo plazo. El análisis estadístico se llevó a cabo mediante la prueba de la t de Student, y se estimó significativo el valor de p < 0,05. El Comité de Ética Científica de nuestra institución aprobó previamente el estudio. Resultados: Se observaron diferencias estadísticamente significativas sólo en cuanto a la variable duración de la estancia hospitalaria. Ningún caso del grupo a laparoscopia se convirtió en cirugía abierta. No se observaron complicaciones inmediatas ni tardías. La pérdida de sangre fue insignificante y no fue necesario administrar transfusiones. Conclusiones: Según nuestra experiencia, la nefrectomía videolaparoscópica transperitoneal presenta resultados similares a los de la nefrectomía abierta, excepto en lo que respecta al tiempo de hospitalización (AU)

Introduction: Laparoscopic nephrectomy in children has become a reasonable alternative to open nephrectomy and has replaced open surgery for many renal diseases. The purpose of our study is to evaluate transperitoneal videolaparoscopic procedures in renal benign diseases in comparison to an open surgery approach. Patients and methods: 34 children aged between 17 days and 15 years old (mean 6.14) were divided into two groups in order to be submitted to nephrectomy. The first one underwent transperitoneal videolaparoscopic nephrectomy and was composed by 21 patients aged from 2 months to 15 years (mean 7.42), from which 12 were females and 9 males. The second group was submitted to open nephrectomy and was composed by 13 patients aged from 17 days to 11 years (mean 3.91), 6 females and 7 males. The groups were compared regarding anesthesic time, operative time, length of hospital stay, postoperative pain and time of reintroduction of oral intake. Short and long term complications were also evaluated. Statistical analysis was performed by Student t-test with the level of significance set at P < 0.05. The study was previously approved by the Committee on Ethics in Research of our institution. Results: Significant statistical difference was observed only for the variable length of hospital stay. No laparoscopy group case was converted to open surgery. There was no immediate or late complication. Blood loss was negligible and no transfusion was required. Conclusions: In our experience, transperitoneal videolaparoscopic nephrectomy has similar results to open nephrectomy, except for time of hospitalization (AU)

Carcinoma in diverticulum of female urethra.

A case of female urethral diverticulum is reported by the authors. It is a rare disease and about 31 cases have previously been described. An analysis is made in relation to the diverticulum of the urethra and to female urethral carcinoma. Emphasis is given on the semiology and the recently acquired diagnostic procedures, as these have led to an increased number of recognized cases. In the case presented, an extended resection and a definitive urinary derivation was performed, together with chemo- and radiotherapy. A follow-up of 2.5 years showed no signs of recurrence or metastases.

[Vesicostomy: a temporary urinary diversion in childhood]. / La vésicostomie: dérivation urinaire temporaire dans l'enfance.

The authors report on 21 pediatric cases of tubeless cystostomies (19 males and 2 females). 15 cases of posterior urethral valves (septic condition and very narrow urethra). 3 primitive vesico-renal refluxes (small bladder, severe impairment of renal function and extensive dilatation of the upper urinary tract). 2 prune-belly syndromes. 1 neurogenic bladder. (Impracticable intermittent catheterization). 19 of the 21 cases showed dramatic improvement (narrowing of the upper urinary tract, disappearance of infection and resumption of staturo-ponderal thrive). Only 1 child with valves had to be put on cutaneous ureterostomy. The improvement in the upper urinary tract, as seen on the IVP, is very rapid in valve cases without reflux. The improvement is visible earlier on isotopic renal scans than on IVP. 11 children suffered acute pyelonephritis during vesicostomy. There were no cases of cutaneous peristomal modification. Simultaneous closure of the derivation and surgery of the primitive disease were performed in 10 cases after a 1-3 year period of vesicostomy. Vesicostomy will succeed in those babies who have shown clinical and biological improvement after a short period of trans-urethral or suprapubic catheterization. The suprapubic endoscopis treatment of the valves becomes possible through the vesicostomy hole excluding urethral trauma.
