Circle nephrostomy tube revisited

Percutaneous Nephrostomy Tube-related Infections

Percutaneous transrenal retrieval of fractured nephrostomy tube under fluoroscopic guidance.

Percutaneous nephrostomy is a safe procedure, performed routinely by interventional radiologists, and has a low complication rate. We report an unusual case of a fractured nephrostomy tube, retained within the kidney, having its fractured end trapped within the healed retroperitoneal tract. The catheter was retrieved by snaring it, using a percutaneous access to the collecting system. We descri...

Percutaneous nephrostomy tube-associated bacteremia caused by Corynebacterium urealyticum.

Corynebacterium urealyticum, an infrequent cause of bacteremia, is an emerging pathogen in humans, especially immunocompromised hosts. This report describes a patient with prostate cancer complicated with obstructive nephropathy who developed C. urealyticum bacteremia after placement of a percutaneous nephrostomy tube. The bacteremia was not controlled until the infected nephrostomy tube was re...

Improved nephrostomy tube can reduce percutaneous nephrolithotomy postoperative bleeding.

Renal hemorrhage is one of the most common and worrisome complications of post-percutaneous nephrolithotomy (PCNL). This study aimed at evaluating the safety, effectiveness of utilization of the absorbable hemostatic gauze cover renal tract for hemorrhage of post-PCNL. The prospective study including 188 patients with upper urinary tract calculi was carried out in the department of Urology at L...

Chiral boson on a circle revisited

It is a well known result that the scalar field spectrum is composed of two chiral particles (Floreanini-Jackiw particles) of opposite chiralities. Also, that a Siegel particle spectrum is formed by a nonmover field (a Hull’s noton) and a FJ particle. We show here that, in fact, the spectrum of the chiral boson on a circle has a particle not present in its currently well known spectrum. PACS: 1...
