Island patch urethroplasty: effects on urinary flow and ejaculation.

Seventeen patients had a single-stage operation for urethral stricture. To avoid recurrence (which occurred in 2 patients) the urethra should be opened not only through the stricture but well beyond the pathological cavernous tissue. In 3 patients it was not possible to reconstruct the bulbocavernosus muscle over the bulb. This resulted in urethral pouching which did not interfere with micturition, except for after-dribbling, but prevented forceful ejaculation and the semen leaked slowly for several minutes. Excision of the apex of the scrotal skin flap to the island patch seems to prevent marginal skin necrosis.

Ruptured renal artery aneurysm in a solitary kidney.

The incidence of renal artery aneurysm in a solitary kidney has not been previously documented in the literature. A case of aneurysmal rupture into a pelvicalyceal system of a solitary kidney, successfully treated by primary vascular reconstruction under the cover of inosine and synchronous pelviureteric repair, is reported.

Poliomyelitis vaccination of infants: preimmunization status and seroconversion.

A study was carried out in Delhi on the preimmunization status of infants aged 2-6 months with regard to poliomyelitis and on seroconversion after the administration of oral poliomyelitis vaccine. It was found that 30.3% of the 204 infants included in the study excreted enteroviruses, 58% of which were found to be polioviruses. Of 197 sera examined for neutralizing antibodies against different types of poliovirus, 73% were found to be triple negative and only 4.0% triple positive. Three doses of oral poliomyelitis vaccine were administered at intervals of 1 month. It was found that 71.8% of the vaccinated infants excreted cytopathogenic agents in the 7 days following the first dose; 80.4% of these agents were found to be polioviruses. Seroconversion was studied in 71 infants, and good antibody responses to all three types of poliovirus were observed.
