Transurethral transvesical endoscopic management of a retrovesical hydatid cyst.

We present a technique of transurethral transvesical endoscopic management of an intraperitoneal retrovesical hydatid cyst. Cystoscopy is performed using a 20.8F nephroscope.

Needle renal displacement technique for the percutaneous approach to the superior calix.

We describe a new renal displacement technique using an 18-gauge needle to facilitate superior calix puncture and consequently to decrease intrathoracic morbidity. Initially, a lower or middle calix is punctured with an 18-gauge needle. Then, the proximal end of the needle is progressively pushed in the cephalic direction.

Endoscopic replacement of the amplatz sheath with a larger one, for larger stone fragments extraction.

We present a technique to replace a 24F with a 30F working sheath during percutaneous renal surgery, for larger stone fragments extraction. To gain time, the 30F sheath is directly glided over the 24F sheath under endoscopic control, without radiation exposure.

A vacuum cleaner for the pelvicalyceal system during percutaneous nephrolithotomy.

Removing small stones, fragments and debris, clots, or clusters of small stones can be bothersome and time consuming. We perform a technique to sweep out fragments from the kidney during percutaneous nephrolithotomy using suction. The nephroscope is used as a vacuum cleaner by adapting the suction tube to the nephroscope operating channel.

[Genital Buschke Loewenstein tumors. Report of 4 cases].

The authors present four cases of Buschke Loewenstein tumor. In three cases, the outcome was good despite areas of anaplasic change are seen in one of them. The outcome of the fourth patient was fatal because of multiples recurrences.
