Organ preserving surgery in testicular epidermoid cysts.

Our experience with 18 patients with simple epidermoid cysts of the testis (monodermal teratoma) is reported. In all patients the tumor was enucleated completely and 2 biopsies of the adjacent parenchyma were obtained for exclusion of associated germ cell cancer, scar or carcinoma in situ. There was no evidence of malignancy in any biopsy specimen.

A conservative approach to bilateral testicular germ cell tumors.

We report on 6 patients with bilateral testicular germ cell tumors treated by organ sparing surgery. Tumors 6 to 30 mm. in diameter were enucleated, and biopsies of the tumor bed and peripheral parenchyma were taken.

Ultrasound in the evaluation of urethral stricture disease: a prospective study in 175 patients.

Objective: To investigate the characteristic ultrasonic appearance of urethral stricture disease in men.

Patients And Methods: Between 1990 and 1992 a prospective study in 175 men with the suspicion of urethral stricture was performed using urethral ultrasound as the first diagnostic procedure, followed by retrograde urethrography, voiding cystourethrography or urethroscopy.

Results: The sensitivity and specificity in detecting urethral strictures were 98% and 96% respectively.

[Malignant pheochromocytoma of the urinary bladder. Case report and review of the literature].

Iatrogenic ureteral lesion is a severe complication in gynecological surgery. We present a case in which the obstruction led to fornix rupture, urine extravasation and urinary ascites. The problematic diagnostic pathway is emphasized.

[Organ saving therapy of bilateral testicular tumor].

Of 368 patients with unilateral testicular cancer, 12 (3.3%) suffered from a second malignant germ cell tumor; five tumors occurred synchronously, seven were treated by bilateral orchiectomy, five were treated by unilateral organ sparing surgery with enucleation of the germ cell tumor in a pilot study. Enucleation was performed for four seminomas and one embryonal carcinoma; an associated carcinoma was found in situ in three cases.

[Is ultrasound imaging of the urethra an alternative to radiologic urethral imaging and urethroscopy?].

Ultrasonographic examinations have been widely accepted in urology for a variety of indications. Stimulated by reports on the usefulness of sonourethrography and the idea of reducing radiation exposure, we examined 145 male urethrae during retrograde instillation of sterile saline solution. In addition, 8 patients were examined during spontaneous micturition.

[Hemangioma of the glans penis. Its therapy by neodymium:YAG laser].

We report the case of a young male patient with a massive cavernous hemangioma of the glans penis that had developed since childhood. The patient complained of pain when standing for long periods and during erections; furthermore its appearance disturbed him for cosmetic reasons. After associated hemangiomas of the genitourinary tract had been excluded by ultrasonography, intravenous pyelogram and cystoscopy, laser coagulation of the hemangioma was performed with a neodymium:YAG laser with the patient under local anaesthesia.

The penile plication procedure: an alternative method for straightening penile deviation.

The number of reported cases of congenital and acquired penile deviation is evidently increasing. We describe our experience with the penile plication procedure, which we used to treat 40 patients with penile deviation. Postoperatively, all patients regained the ability for sexual intercourse, with potency remaining unimpaired.

[Systemic alpha-interferon therapy: a possible method for prevention of testicular atrophy and permanent sterility in patients with bilateral mumps orchitis].

In postpubertal men orchitis is the most common complication of mumps infection, occurring in 5-37% of this population. A bilateral manifestation is observed in 16-65%. The most important danger is the risk of developing testicular atrophy, which results in sterility.

[Asymptomatic paraganglioma of the bladder wall with unusual extensive submucous vascular proliferation].

Paraganglioma of the urinary bladder is a very rare tumor, which is usually diagnosed on the basis of its endocrine symptoms because of the excretion of vasoactive substances. One case of asymptomatic paraganglioma detected by chance is described, it was misdiagnosed as hemangioma because of its marked suburothelial vessel proliferation.

[Results of close testicular tumor after-care].

Close monitoring schedules for patients with malignant germ cell tumors improved cure rates, since early detection and treatment of tumor recurrences was possible. In a retrospective analysis we evaluated 210 of 274 patients with malignant germ cell tumor, 189 (90%) of whom achieved complete remission after primary therapy. There were 15 patients (7.

[Adjuvant systemic interferon alpha-2B treatment in treatment refractory anogenital Condylomata acuminata].

Despite different treatment modalities, resistance to treatment is observed in 4-15% of patients with anogenital condylomata acuminata. A total of 16 patients with resistant condylomata acuminata or extended infection affecting an area of more than 6 cm2 were treated with a prospectively defined therapy entailing laser treatment and adjuvant systemic interferon-alpha 2B (3 x 1 MU/day for 7 days). Of the 16 patients, 13 (81%) were in complete remission after an 8-month period of follow up.

[Penis plication-plasty--an alternative to the treatment of penile deviation].

Congenital and acquired penile curvature are observed increasingly often. A new surgical technique (plicating procedure) was applied in 27 patients with penile deviation. All patients retained potency, and 96% were completely satisfied with the functional result of surgical correction.

[Adjuvant 5-fluorouracil lacquer administration for reducing the rate of recurrence of condylomata acuminata following laser surgery treatment].

In the recent past we have observed HPV-induced condylomata acuminata with increasing frequency. Providing 60-80% complete remission the laser coagulation is primary in the treatment of condylomata acuminata. However, the generalized mucosal infection with subclinical condylomata acuminata leads to a recurrence in 30-70% of cases.
