[Epididymal tumors (author's transl)].

Six cases of benign primary epididymal tumor have been investigated in our patients. The tumor size fluctuated between 3 and 35 mm in diameter. Frequency, histology and medical development are described. The majority of epididymal tumors (53%) is comprised of so-called adenomatoid tumors of benign nature and their histogenesis is being discussed. The difficulties of differential diagnosis are pointed out. Since malignity exists in 26% of the cases, the surgical exposure and diagnosis by frozen section is being postulated, when suspicion of epididymal tumor becomes evident.

[Results of radical perineal prostatectomy: 14 years' experience (author's transl)].

One hundred radical perineal prostatectomies are reported, which were performed during the past 14 years. In this series were 36 patients with stage C carcinomas, which could not be operated radically by total prostatectomy. This shows the difficulties in preoperative staging of these tumors. In spite of doing routinely a vesiculography and a lymphography these tumors were frequently undervalued. The 5-year survival rates, being 66.6% in stage A/B and C carcinomas correspond nearly to the results of Belt. The postoperative incontinence rate was 10%. Only two patients retained their potency. There were no postoperative mortalities.

[Experiences with various antireflux operations (author's transl)].

One hundred and thirty-eight antireflux operations in 94 patients are reported from 1964 to 1974. Bischoff's method was used 44 times with 63% successful results; Lich/Grégoir's method 38 times with 77% success; and Politano/Leadbetter's method 50 times with 92% success. Indications are briefly investigated.

[The diagnostic value of radiological, nuclear medicine and biochemical methods for detection of bone metastases in carcinoma of the prostate (author's transl)].

785 combined diagnostic procedures are reported which were carried out on 353 patients with microscopically proven carcinoma of the prostate in order to detect metastases. X-ray films of the thorax, spine and pelvis were taken. Also bone-scintigraphy was done with 87MSr or 99MTc-polyphosphate. Additionally the alcaline, acid and prostate phosphatases were determined. A diagnostic coincidence between radiological results and bone-scan was found in 95.1% of cases. The bone-scan was false negative in 3.7%. Only in 1.2% metastases were detected earlier by the bone-scan than by x-ray examinations. Referring to the number of studies identical results were found. In roentgenologically detected metastases an increased serum level of the alcaline phosphatase was found in 61%, of the acid phosphatase in 31% and of the prostate-phosphatase in 25%.

[Echinococcal infection of the kidney (author's transl)].

800 echinococcal infections of the kidney have been described in the world literature, nevertheless, here this disease is very rare. As a result of increasing tourism and employment of workers coming from endemic areas, the morbidity rises and the clinical picture gains in importance. A review has been made of epidemiology, life cycle and symptomatology of the cystic echinococcus and the diagnosis, differential diagnosis and therapy of this parasitosis has been discussed with reference to two misdiagnosed cases from our own patients.

[Experience with a one-stage hypospadias repair (author's transl)].

33 single-stage hypospadias repairs are reported, which were performed within 2 years. The operative technique is described. In two cases, fistulas developed and required operative treatment. The average follow-up was 13.5 months. 28 cases showed good functional and cosmetical results. Three cases required additional surgery to improve the cosmetical result. The Allen-Spence-Hoffman-Hall one-stage technique has proved to be suitable to correct a distal hypospadias without chordee.

[Comparative investigations in closing nephrotomies with conventional suturing technique and dura ribbons (author's transl)].

On 13 rabbits total longitudinal nephrotomies were performed on both kidneys. On the right side the margins of the parenchyma were sutured together with figure eight sutures. On the left, the nephrotomies were closed by tying ribbons of human dura around the kidney. Excretory urograms after 4-8 months showed no differences on both sides. On histological examination there was no difference of the scars. After roentgenological and histological criteria there are no advantages by closing kidney wounds with dura ribbons versus conventional suturing technique.

[Studies on the reaction of the rabbit testis after ligation of the arteria and vena testicularis compared with ligation of the vein alone].

In surgical treatment of Varicocele compete the ligation of the V. testicularis (Ivanissevich/Bernardi) with the ligation of the A. and V. testicularis (Palomo). Because there are doubts against throttling the arterial blood supply of a previous damaged testis, the effect of ligation of A. and V. testicularis on the testis was studied and compared with the ligation of the vein alone. On 18 adult rabbits either the Palomo operation was performed on one side, leaving the contralateral side as control, or on one side only the vein was ligated and on the other side artery and vein were ligated, permitting, so a direct comparison on the same animal. All the testes were examined histometrically. In the control group the diameter of the tubuli increased from 218 mu after 3 months to 253 mu after 10 months. In the Palomo-group the diameter decreased from 153 mu after 3 months to 82 mu after 6 months, and increased again to 153 mu after 10 months. In the Bernardi-group no differences to the normal testes were found.

Replacement of tunica albuginea of corpus cavernosum penis using human dura. Experimental study on dogs.

The tunica albuginea of corpus cavernosum penis was excised and replaced with human dura in experiments on 11 dogs. The surface of the implant epithelialized within three weeks, and later the implant was replaced by autologous tissue with no scarring and shrinkage. After resection of placques in Peyronie's disease the tunica albuginea can be replaced with specially treated human dura.
