[Urethrovesical reflux in patients with chronic cystitis].

We studied the role of urethrovesical reflux in the onset and maintenance of chronic inflammation in the urinary bladder in patients suffering from chronic cystitis combined with pseudopolyposis of the neck of the bladder and proximal part of the urethra. We modelled a simplified version of an urination fragment of a special computer graphic station. The original computer model theoretically proves the existance of urethrovesical reflux caused by pseudopolyposis in the zone of the urinary bladder cervix and/or proximal urethra.

[Combination surgery in radical nephrectomy].

In 18 of 487 patients (11 males, 7 females) operated for renal cancer, radical nephrectomy was made simultaneously with cholecystectomy (n = 14) and prosthetic repair of the abdominal aorta (n = 4). A transabdominal approach was used in all the cases. Duration of radical nephrectomies from the transabdominal approach varies from 95 to 180 min while simultaneous operations lasted from 130 to 228 min.

[Transposition of the distal urethra in surgical treatment of recurrent lower urinary tract infection in women].

One of the procedures used in surgical treatment of recurrent infections of the lower urinary tracts is transposition of the distal urethra. This procedure was used in 27 females. Persistent clinical recovery was achieved in 81.

[High colpocleisis in the treatment of postradiation vesicovaginal fistulas].

Surgical treatment with application of the modified technique of high colpocleisis according to Latsko was performed in 174 patients aged 26-72 with postradiation vesicovaginal fistulas. The latter developed 6 months to 26 years after radiotherapy. The operation resulted in restoration of the urinary bladder capacity and spontaneous urination.
