Consecutive vesicovaginal fistula for transobturator sling perforations and successful repairs with skin flap.

AIM: To report a reconstructive technique of large vesicovaginal fistula repairs, which is a rare complication of the most modern anti-incontinence procedures (tension-free tapes) using the "oldie but goodie" Lehoczky's island flap. METHODS: Women with large vesicovaginal fistulas caused by mid-urethral transobturator tape were operated in our department. The transobturator tape was removed and the large fistula was closed using the skin island flap. The flap was created from the regional skin and subcutaneous tissue and pulled with intact vascular supply through a paravaginal tunnel to the site of the vaginal defect. RESULTS: No complications occurred after the reconstructions. The patients have become permanently continent and free from fistulas. CONCLUSIONS: Mid-urethral transobturator sling is a successful procedure evidenced worldwide with a very low rate of fistula formation. Lehoczky's island flap can be a reasonable and safe surgical option in the repair of large defects of the vaginal wall.

[New perspectives in studies of the urogenital tract microcirculation--a decade of experience in Szeged, Hungary]. / Az urogenitális traktus mikrokeringési kutatásainak módszerei, új perspektívái--egy évtized szegedi tapasztalatai.

Investigations in microcirculation are an essential way to understand basic pathologic mechanisms and detect early signs of various diseases. Up until the last decade there was only limited amount of information available in the field of urological microcirculation. Due to advanced technologies, new methods and international cooperation of the research team of University of Szeged, promising new data became available in this interesting field.

Metachronous clear cell carcinoma of the tongue and kidney: a diagnostically challenging coincidence.

Clear cell carcinomas (CCCs) account for 1% of carcinomas of the salivary glands. A 63-year-old woman presented with a painless, nonulcerated, nodular mass on the right side of the tongue, without palpable neck nodes. After excision and cryotherapy of the mass, the histologic evaluation revealed CCC. At the age of 55, she had undergone radical nephrectomy for CCC of the kidney which extended into the renal vein (pT3aN0). Although she had remained metastasis-free during the follow-up, the clear cell morphology raised the possibility of late lingual metastasis of the renal CCC. A clinical search for metastases, and a series of immunostainings and analysis of the von Hippel-Lindau gene were therefore performed on paraffin-embedded blocks of both tumors: Primary metachronous CCC of the tongue was diagnosed. This case illustrates the diagnostic challenge posed by CCC of the tongue if there is a history of CCC of the kidney.
