Visual sexual stimulation plethysmography: complementary test to nocturnal penile plethysmography.

Diurnal penile plethysmography under visual sexual stimulation (VSS) and nocturnal penile tumescence (NPT) plethysmography have been performed in 5 healthy volunteers and 195 consecutive men complaining of impotence. Our study demonstrates that VSS plethysmography may compensate at least partially for the shortcomings of classic NPT plethysmography, by allowing direct clinical estimation of "erectile performance." Twenty percent of the patients had full erection under VSS. These patients do not need further testing. VSS is a noninvasive and useful "first-line" investigation in erectile dysfunction.

Polyorchidism: report of three cases and further embryological considerations.

We report 3 new cases of polyorchidism. Review of the literature allows two groups of anatomical variations to be identified: (1) where the Wolffian duct is duplicated longitudinally or absent, and (2) where the two testes are drained by the same epididymis and vas deferens. We postulate that the first group results from a primary anteroposterior division of the genital ridge, whereas the second group is the result of a transverse duplication.

[The value of laparoscopy in the diagnostic evaluation of cryptorchism with non-palpable testicles].

From 1986 to 1989, diagnostic laparoscopy was performed in 12 boys, before operation of non-palpable testes. Cryptorchidism was unilateral in all but one case. Preoperative physical examination and ultrasonographic studies of the inguinal region had been performed in all of them and failed to localize the testis. Laparoscopy demonstrated six intra-abdominal testes in five children: five testes were brought down into the scrotum and one was removed because endoscopic diagnosis of complete epididymo-testicular dissociation. Four of the seven other boys were not operated on because of laparoscopic findings. In the last three cases, systematic surgical exploration of the inguinal region was performed and demonstrated total atrophy of the testis. Performed in good condition the procedure is very safe and simple to achieve. It does not increase significantly the duration of the operation and gives objective elements for the operative procedure.

[Tethered cord syndrome, conservative or surgical approach?].

The authors gave a definition of a filum terminale and discussed the symptomatology, the etiology and the pathophysiology. They stressed the importance of carrying out a full neurophysiological, orthopaedic, anal and urogenital examination. This is the only way of establishing an indication for surgical treatment that should be carried out early in order to minimize acute accidents.

Endoureteropyelotomy: percutaneous treatment of ureteropelvic junction obstruction.

A total of 47 percutaneous operations (endoureteropyelotomy) was performed for treatment of 41 congenital and 6 secondary cases of ureteropelvic junction obstruction between September 1983 and April 1988. Evaluation was available in 39 cases with a followup of 4 to 56 months (mean 16 months). Good results were obtained in 28 of 39 cases (72 per cent) and there were 3 failures (8 per cent). Eight patients (20 per cent) were symptomatically improved but they had residual obstruction on a diuretic study. Only 1 multioperated patient with a good early postoperative result has shown radiological deterioration at 1 year. Complications were managed conservatively, except for 1 case of intravascular coagulopathy. Endoureteropyelotomy is an effective alternative treatment for ureteropelvic junction obstruction but further evaluation definitely is warranted to define better its indications and risk factors.

[Urodynamic and electrophysiologic studies in evaluating congenital neurogenic bladder].

We investigated 50 patients with a congenital neurogenic bladder secondary to myelomeningocele (38), sacral agenesis (5) and occult spinal dysraphism (7). There were 25 males and 25 females, aged from 1 month to 29 years (mean age at the time of evaluation was 9.2 years). Pressure-Flow-EMG study was obtained in every instance. In addition, 25 patients underwent electrophysiological testing (sacral reflex arc testing and somatosensory evoked potentials from the pudendal nerve). The patients were then classified according to the urodynamic and electrophysiological results. We allocated the patients into a "functional" classification as recommended by Van Gool. This classification is useful in the selection of proper therapy, and in the definition of the risks of upper tracts deterioration.

[Ureteral lithiasis. Development of the therapeutic strategy and the place of endoscopic treatment].

In order to evaluate the impact of endourological techniques and extracorporeal lithotripsy on the management of ureteral calculi, we reviewed the charts of 838 patients requiring hospitalization for this pathology from 1982 till 1987. 314 patients were managed conservatively and 524 required intervention therapy: 52 with blind endoscopic techniques, 93 with open surgery, 122 with retrograde ureteroscopy, 168 with percutaneous extraction and 92 with ESWL. Evolution of the therapeutic strategy is discussed and our present approach to ureteral stone management is outlined.

Age related flow rate nomograms in a normal pediatric population.

Uroflow studies in a normal pediatric population were analysed statistically. Single studies for 511 subjects (272 boys and 239 girls) were reviewed. Nomograms relating peak flow to volume voided and age were established. An acceptable lower limit for peak flow was obtained from the data and a volume voided range was calculated so that both criteria could be used with 90% probability to define the normal voiding situation. The mean values of peak flow rate increased with volume voided in both sexes and also with age in the male population. Different sets of nomograms, which are necessary for daily clinical evaluation, are given. They define the normal values in the normal population.

Body surface related flow rate nomograms in a normal pediatric population.

Uroflow studies for 511 normal pediatric subjects (272 boys, 239 girls) were analyzed statistically. Nomograms relating peak flow to volume voided and body surface were established. An acceptable lower limit for peak flow was obtained from the data and a volume voided range was calculated so that both criteria could be used with 90% probability to define the normal voiding situation. Body surface area was found to be a more reliable index than age in the establishment of nomograms. In the male population the 90% probability applied to a significantly greater volume voided reliability. In the female population mean peak flow rate rose with increased body surface. Finally, in both sexes the 10% lower limit was closer to the regression mean, allowing a tighter distribution around this value.

Clean intermittent catheterization in congenital neurogenic bladder.

The aim of our study was to evaluate clean intermittent catheterization in children and young adults with congenital neurogenic bladder dysfunction. Thirty-four patients with a follow-up of more than 3 months were included in the study. Eighty-six % of patients observed a reduction of the urinary infection rate. Urinary continence improved in 91% (however among these patients 82% also took either anticholinergic or alpha-stimulating drugs). In 46% of the subjects an improvement of the upper tracts was observed. No major complication was observed.

[Hypospadias: surgical aspects and personal experience].

In the last eight year period, a series of 102 hypospadias reconstruction performed in our institution were reviewed. 50% presented with marked degree of chordee. Four types of repair where used: MAGPI (n degree 18), Mathieu (n degree 41), Duckett (n degree 28), two stage repair (Duplay) (n degree 12), other procedures (n degree 3). Overall complication rate was 18% and was related to major procedure and difficult technical situations. It never compromised the final outcome of the procedure. The relatively high complication rate mentioned in the literature and in our series emphasizes that hypospadias surgery has to be done by well trained surgeons in this field.

[Sexual ambiguity: urologic aspects].

Ambiguous genitalia require prompt decision in the neonatal period to give the child the best opportunity to avoid later major problems of sexual identification. A team approach including the neonatologist, the pediatric endocrinologist, the geneticist and the pediatric urologist seems to be the best way to make the right decision. This paper is a review of 48 cases of ambiguous genitalia referred to our center for management. The diagnosis of female pseudohermaphroditism was established in 30 cases with 21 presented with adrenogenital syndrome. Ten patients were considered as having a diagnosis of male pseudohermaphroditism, six presented with gonadal dysgenesis and two were true hermaphrodites. Principles of surgical management for each category of patients is exposed, discussed and will be the way to treat subsequent cases.

Pudendal cortical somatosensory evoked potentials.

To determine normal reference latencies pudendal cortical somatosensory evoked potentials were evaluated in 20 healthy volunteers. The dorsal nerve of the penis or clitoris was stimulated electrically and the cortical response was recorded from the CZ-2 point (2 cm. behind the central vertex). Reproducible responses were obtained and reference values were established.

Treatment of localized neuroblastoma.

The treatment of neuroblastoma must take into account the prognosis as determined at the time of diagnosis. The stage is an important prognostic factor. In Evans's Stage I neuroblastoma, surgery is curative in itself and adjuvant treatment is not needed. In Evans' Stage II, it is our opinion that the presence of involved lymph nodes worsens the prognosis. Therefore, we suggest that patients with Stage II should be divided into Stage IIA (without lymph node involvement) and Stage IIB (with lymph node involvement). The treatment of Stage IIA patients may be the same as for Stage I patients, i.e., surgery alone. However, Stage IIB patients should be treated with intensive combined chemotherapy of short duration following surgery.
