Ces Urol 2003, 7(1):5-7 | DOI: 10.48095/cccu2003001 
Introduction: The authors aim to drive attention to the importance of urological examination in infertile and subfertile males before starting therapy with methods of assisted reproduction by using the example of possible detection of such a serious disease as malignant testicular tumour by means of a retrospective analysis of diagnostic summaries in patients investigated during 17 months in the andrological clinic of University Andrological Centre in FN Brno. Material and methods: 224 patients refferred for subfertility or infertility and abnormal spermiogram were seen for the first time in the andrological clinic of the University...

The authors present a cohort of patients with a tumor of upper urinary tract in whom the coincidence of bladder urothelial carcinoma was surveyed. 48 patients with urothelial carcinoma of upper urinary tract were diagnosed and underwent surgery from 1988 to 1998. Patients were followed up for 14 to 144 months after surgery. The coincidence of carcinoma of upper urinary tract and urinary bladder was observed in 44% (21 patients). When comparing the grading of upper urinary tract tumours with bladder tumours, in 52% it was the same, in 38% higher and in 10% lower. The maximum of incidence was in the seventh decade (48% patients). A higher incidence was...

The aim of the study is to evaluate the role of fluorescence cystoscopy in the diagnosis of urinary bladder tumours. 125 fluorescence cystoscopies altogether were done in 105 patients with suspected urinary bladder tumour in our hospital since 1997. 5-aminolevulic acid was instilled intravesically by a thin catheter 1,5-3 hours before the procedure, the source of excitation light used for investigations was produced by Delong Instruments resp. Olympus companies. Patients were investigated in both white and violet light, exophytic tumours were removed and biopsies were taken from suspected areas in both investigations. 437 specimens of the tissue were...

The authors give a report of their active approach to patients suffering from a serious affection of the urinary tract caused by tumours of gynaecological or colorectal origin. They present a set of 16 patients suffering from gynaecological malignity and 6 patients suffering from rectosigmatic adenocarcinoma, who at the time of examination had no proved distant organ metastases. The patients' Karnoffski index ranged from 100 to 60. Their life expectancy exceeded six months. Due to the complete obstruction of pelvic sections of ureter or due to tumorous infiltration of the urinary bladder they were turned down to a permanent external urine drainage,...
Small cell carcinoma of urinary bladder - case report

Small cell carcinoma of urinary bladder is a rare disease with poor prognosis. About 150 cases are reported in the literature. The tumour is characterized by an aggressive growth with local spreading and remote metastases. The invasion of the tumour to the muscle of the bladder or to paravesical fat is present in most patients at the time of diagnosis and the incidence of metastases is high as well. The tumour has two basic histological forms, a pure small cell carcinoma and mixed, together with urothelial carcinoma of the bladder. Imunohistochemical investigation is essential for the diagnosis. Management consists apart from surgery of chemotherapy...
The expression of potassium channels in human detrusor muscle
J. Krhut, D. Hammerer, S. Hering, H. Madersbacher
Ces Urol 2003, 7(1):25-28 | DOI: 10.48095/cccu2003006
Potassium channels are proteins, the function of which is to transport potassium ions accross the plasma membrane of cells. Their important function was proven especially in muscular and neural cells, where they participate in an important way in the regulation of cellular excitability. The aim of the work is the imunohistochemical detection of potassium channels in the tissue of human detrusor muscle. Detrusor biopsies of 16 patients altogether were investigated by polyclonal antibodies against potassium channels subtypes KCa (calcium-gated potassium channels) and KV (voltage-gated potassium channels). Immunohistochemically we proved an excessive...
Transurethral injection of botulinum toxin in the treatment of neurogenic hyperactivity of the detrusor muscle
J. Krhut, J. Kopecký, K. Mainer
Ces Urol 2003, 7(1):29-32 | DOI: 10.48095/cccu2003007
Neurogennic hyperactivity of the detrusor muscle is one of the typical consequences of the impairment of innervation of lower urinary tract at the level of upper motor neuron. The depression of the detrusor muscle activity with anticholinergics together with intermitent catheterisation is used in treatment, surgery is used in refractory cases. Botulinum toxin A is a neurotoxic substance isolated from Clostridium botulinum, causing the blockade of release of acetylcholin from presynaptic membrane. The aim of the study is to prove the effectivity of botulinum toxin treatment in patients with neurogenic hyperactivity of the detrusor, resistant...

Ces Urol 2003, 7(1):33-36 | DOI: 10.48095/cccu2003008
The authors compared the effectiveness of standard diagnostic procedure and 3D reconstruction of ultrasonography in a group of 22 patients. The ultrasonography was independently evaluated from the record by two physicians - an expert and a sonographist in training. The aim was the differentiation between localized and locally advanced carcinoma of the prostate. The criterion was the histological examination of the prostate after radical prostatectomy. The 3D analysis was more successful in both sonographists (88% resp. 66%) than standard procedure (59%). The sensitivity of 3D sonography was 82 (resp. 66%), the specificity was 100% (resp. 57%). 3D transrectal...

F. Záťura, R. Vrtal, R. Fiala, M. Očenášek, J. Rosenberg, J. Křen, M. Rosenberg
Ces Urol 2003, 7(1):39-41 | DOI: 10.48095/cccu2003009
The authors report of a technical innovation destined for routine investigation of urodynamic methods, originating from the observation of urine leak from urethra. They used the videourodynamic inlet of the apparatus and they connected it with standard endoscopic optical device with a cammera, which enables a very precise scanning of urethral ostium synchronically with pressure curve of intravesical and intrabdominal pressures and EMG. The leak of urine can be analysed from the recording of the urodynamic protocol.

The authors used the technology of multi-channel static perfusion urethral profilometry with the aim to compare pressure values in individual channels and to find the information value of one channel only to evaluate the validity of standard one-channel static profilometry. They investigated a group of 25 patients with the method of four-channel static profilometry. The group consisted of patients with incontinence, BHP, urethral stricture, after RAPE and TUR. They proved, that the pressures in individual channels are so different, that the standard method of static profilometry is not reproducible and renders dianostic information of poor validity....
