[Results following microsurgical epididymovasotomy].

The chance of refertilization in patients with obstructive azoospermia increases using microsurgical operation techniques. For the establishment of the therapeutic concept the excluding or confirming diagnosis of a distal obstruction of the spermatic canal by means of the preoperative vasovesiculography is necessary. In 19 patients with an obstruction in the transitional zone of epididymus and spermatic duct after epididymovasostomy the patency of the spermatic canals was achieved in 56% of the cases and a conception rate of 22%.

[Bladder neck strictures following transurethral resection--limits of transurethral therapy].

Primary strictures of the vesical cervix probably do not occur more frequently following TUR than after transvesical adenomectomy, but, unlike the latter, they are in greater danger of recidivation under continued transurethral therapy. There is clearly a striking disposition with small primary adenomas. Our own patients are taken as the basis for some thoughts on a few aetiologically effective TUR-specific risk factors and therapeutic conclusions.

[URO-103--a new uroflow measuring device].

A new uroflow measuring instrument produced in the GDR by W. Rentsch , the Uroflow -Recorder URO-103, is presented and compared with thermistor and capacity-measuring apparatuses. The Uroflow -Recorder gives strictly linear measurements and requires extremely little maintainence . Over the test period of 8 months it functioned free from disturbance. The new apparatus is recommended for use, whereby it is suitable for combined urodynamic measurements.

[Testicular torsion and fertility--attempt at prognostic significance].

Following a short presentation of the aetiology and clinical picture of testicular torsion, the results of the treatment of 40 patients are given. In 55% of the patients, with an average age of 16.5 years, the organ was lost, mainly due to primary ablation of the testicle. The cause of this was mainly the delay due to the condition not being recognized by the physician first consulted. In future more attention must be paid to the negative effects of torsion on fertility. Follow-up spermiograms revealed pathological values in 74% of the patients investigated.

[Problems of fever after surgery of the bladder neck. How to classify the causal efficiency of reflux mechanisms].

Fever following operations on the vesical cervix was analysed in 167 patients, whereby the closing of the ostia was observed. Vesicoureteral reflux caused by lesion of the trigonal unit in the region of the inner vesical sphincter causes parenchymatous infection of the kidney to a lesser extent than expected. The specific conditions after the removal of an adenoma of the vesical cervix, with heavy bleeding, the necessity of urine drainage with all its weak points, the high level of bacteria in the urine combined with a delayed epithelization of the "inner wound" can be the starting point for a rise in temperature, whereby haematogenous pyelonephritis is of special significance. A decision on the expediency of antibiotic therapy should in any case only be made after obstructive and locally retentive processes have speedily been excluded as possible causes.

[Surgical treatment of distal seminal duct obstruction].

Transurethral resection of the colliculus seminalis offers a method of removing obstructions in the region of the ductus ejaculatorii. Treatment of post-gonadal azoospermia is problematic since, even if the seminal duct is made passable, the sperm quality remains unsatisfactory. Impairment of sperm motility and spermiogenesis itself is suspected as the expression of an auto-immune reaction to distal obstruction.

[Thoughts on the radical intervention of transurethral electroresection in bladder cancer].

As part of an operative intervention spectrum transurethral electroresection has a considerable breadth of indications for curable carcinomas of the bladder. In order to make use of it for radical surgery one must, on the one hand, perform technically subtle, standardized additional resections in order to confirm that the tumour has been exterminated from the healthy tissue, and, on the other hand, respect limits set by localization and infiltration. Technical and tactical problems and the method of guaranteeing radicality are presented along with a curative-operative integration programme.

[Perforation in TUR].

In the TUR, particularly in clinical teaching is always to be reckoned with extraperitoneal perforation, atypical intraperitoneal perforations are to be taken into consideration. On the other hand it is necessary to prevent the development of a perforation-syndrome. The cystogram has the highest diagnostic value and is at the same time decision aid for the rapid performance of operative and conservative measures. Also with regard to the not infrequent subclinical through-resections the cystogram should become routine examination after every TUR. A clear directive for the resection team and the carrying-through of a consequent behaviour regime for the nursing staff of the hospital are the basis of a successful transurethral resection treatment.
