[Long-term results of urethrectomy following termino-terminal urethrorrhapy for urethral stenosis. A study of 18 cases]. / Résultats à long terme des urétrectomies suivies d'urétrorraphie termino-terminale pour sténose de l'urètre. Etude de dix-huit cas.

Urethrectomy followed by terminoterminal urethrorraphy is one of the oldest surgical techniques for treating short urethral stenoses, regardless of their location. Eighteen patients managed by this technique were followed-up for at least ten years. Results were satisfactory in four out of every five cases and success was nearly immediate. No delayed deteriorations were seen. These limitations are mainly related to the length of the lesion.

Attempts to enhance kidney allografts in DLA-identical dogs with specific anti-IA-like sera.

Attempts at enhancement of kidney allografts in DLA-identical dogs by injection of specific antidonor Ia-like antibodies or IgG are reported. Anti Ia-like sera were raised by immunization with allogeneic, splenocytes and subsequently adsorbed on platelets from the immunizing dog. Platelets were obtained from an average of 20 plasmaphoreses of each immunizing dog and from a pool of random mongrel dogs. No statistical differences were noticed either in survival time or blood urea levels in pairs of DLA-identical recipients (SD identical and negative mixed lymphocyte culture (MLC) engrafted with either the right donor kidney along with control normal dog sera or the left kidney of the same donor along with the specific antidonor Ia-like sera or IgG. The data indicate that an enhancement procedure easily performed in rodents is not reproducible in dogs.
