Speedy elimination of ureterolithiasis in lower part of ureters with the alpha 1-blocker--Tamsulosin.

Background: Alpha-I blockers decrease the tension and release the spasm of smooth muscles and thus lessen the obstruction and irritation symptoms in the lower urinary tract (LUTS). They make a faster passing of calculi from the terminal part of the ureters possible.

Objectives: The goal of this study was to objectively assess the improvement of difficulties caused by obstructions in ureterolithiasis localized in the lower part of the ureters of 104 randomly chosen patients (pts.

[Hemodynamic changes in varicoceles and their relation to fertility].

Hemodynamic changes in the vascular bed of the affected testis were studied in 45 sterile and 6 fertile patients with varicocele. The examination method used was modified abdominal angiography. The most frequently recorded change in the arterial bed was persistence of the contrast medium in the left internal testicular artery (5 patients).

The influence of various aetiopathogenetic factors on testicular function.

Three hundred and seventy-one patients with azoospermia were examined by means of testicular biopsy. The patients were assigned to seven histological groups according to the degree of damage found in their germinative epithelium. The degree of damage to the germinative epithelium was correlated with the aetiopathogenetic factors.

On the psychopathology of patients with disorders in the descent of the testis.

The authors deal with disorders in the descent of the testis and analyse the causes and manifestations from the point of view of fertility and indications to medical treatment or early surgery. Thirty-nine patients were examined and diagnosed as unilateral or bilateral cryptorchism and retention of the testis. The spermatogenetic functions in individual diagnosis and type of operation are described.

Congenital anomalies of the seminal ducts.

The frequency of individual congenital anomalies of the deferens, the seminal vesicles, the ejaculatory ducts and the utricle in 158 patients treated for sterility was determined by the method of deferentovesiculography by punction. Congenital anomalies were found in 14 patients (8.8%).
