Dislodgement in Long-Term Patients with Nephrostomy Tube: Risk Factors and Comparative Analysis Between Two Catheter Designs
2020
Objective: To determine possible risk factors for accidental nephrostomy tube dislodgement and compare two different tube types in this context in patients with chronic catheters. Materials and Met...
Contemporary Management of Struvite Stones Using Combined Endourologic and Medical Treatment: Predictors of Unfavorable Clinical Outcome
2016
Struvite stones have been associated with significant morbidity and mortality, yet there has not been a report on the medical management of struvite stones in almost 20 years. We report on the contemporary outcomes of the surgical and medical management of struvite stones in a contemporary series.A retrospective review of patients who were treated with percutaneous nephrolithotomy (PCNL) for struvite stones at Duke University Medical Center between January 2005 and September 2012 identified a total of 75 patients. Of these, 43 patients had adequate follow-up and were included in this analysis. Stone activity, defined as either stone recurrence or stone-related events, and predictors of acti…
Laparoscopic laterally extended endopelvic resection procedure for gynecological malignancies
2020
ObjectivesPelvic side wall infiltration by gynecological malignancies has been considered for a long time an absolute contraindication to curative resection. The development of the laterally extended endopelvic resection (LEER) has challenged this surgical paradigm. Although the LEER has been standardized in open surgery, only small studies have been published about its endoscopic feasibility. The objective of this study is to analyze the safety of LEER in patients with gynecological malignancies involving the pelvic side wall.MethodsWe retrospectively evaluated a consecutive series of patients who underwent a laparoscopically modified LEER between July 2014 and November 2018. This indicate…
Transrenal ureteral occlusion using a detachable balloon
1984
Percutaneous transrenal ureteral occlusion using a detachable balloon filled with silicone was performed in 20 patients. The main indications were palliation of large urinary fistulas and as a treatment of last resort for severe dysuria in patients with advanced pelvic malignancies. In 6 patients the contralateral kidney was rendered nonfunctional to obviate the need for bilateral nephrostomy. Due to frequent obstruction of the tube, ureteral blockage in 3 became insufficient. Two dislocated balloons were extracted percutaneously and replaced. In order to achieve effective interruption of urinary flow down the ureter, well-functioning external nephrostomy drainage is necessary.
CT-guided nephrostomy–An expedient tool for complex clinical scenarios
2018
Abstract Introduction & objectives Percutaneous nephrostomy [ 1 ] has emerged as a pivotal approach in the therapeutic management of the obstructed urinary tract. A consecutive incorporation of ultrasonic and radiographic guidance, the approach experienced an almost ubiquitious distribution while most centers currently applying either one or both of these tools jointly. However, success of ultrasound-guidance is limited in obese patients and non-dilated uropathy. In turn, fluoroscopy usually requires an opacification of the urinary collecting system by intravenous or antegrade contrast media injection, which might be harmful for already impaired renal function, raise intrapelvic pressure an…
Transrenal Ureteral Occlusion with a Detachable Balloon
1982
Transrenal ureteral occlusion using a detachable balloon was successfully employed to stop urinary flow in seven patients. The balloon was filled with low-viscosity silicone rubber and released in the distal ureter. Percutaneous nephrostomy provided external drainage. Indications were painful dysuria and large urinary fistulas in advanced pelvic malignancy. The method is preferable to ureteral embolization with tissue adhesive.
A giant fetal urinoma in a neonate without detectable obstructive uropathy
2003
UNLABELLED Fetal urinoma is an uncommon finding in prenatal investigations. Most previous reports have, almost in every case, referred to the presence of an obstructive uropathy and thus to very high pressure in the upper urinary tract during fetal life. In this paper we present a prenatally detected fetal giant urinoma occurring in the absence of an apparent obstructive uropathy but associated with an ipsilateral vesico-ureteral reflux. CASE REPORT A 5-day-old boy, born after a caesarean section in the 37th week of gestation, but without any perinatal distress, came under our observation because of the evidence of a right upper quadrant abdominal mass. This mass had already been detected p…
Choosing the nephrostomy size after percutaneous nephrolithotomy.
2011
Purpose: To evaluate the effect of nephrostomy tube size on perioperative outcomes of percutaneous nephrolithtotmy (PCNL). Methods: Forty-five well-matched patients with normal renal function were prospectively divided in two nonrandomized groups after uneventful PCNL (to receive either a 22-Fr, group 1 (n = 24 pts), or a 12-Fr nephrostomy tube, group 2 (n = 21 pts)). In all a balloon nephrostomy catheter with detachable funnel (Rüsch Teleflex, Germany) was used. A Visual Analogue Scale (VAS) for measuring the pain was administered 8 and 24 h after the procedure. Postoperative analgesics use (Ketoralac Tromethamine 30 mg), pre- and postoperative Hb, renal function and urinary leaks were reg…
Experience with palliative percutaneous nephrostomy in bladder cancer patients
1985
Minimal percutaneous nephrostomy as a palliative urinary diversion was performed in 50 patients with advanced bladder cancer disease. The average survival time was 6.6 months, with 38% of the patients alive after 6 months. Although 88% of the patients died within one year, 2 (5%) are still alive after more than 2 years. Each case of palliative diversion is an individual one, with many different factors influencing the decision. Prolonging life cannot be an indication for diversion. Percutaneous nephrostomy in combination with other percutaneous techniques provides the urologist with excellent therapeutic tools to avoid surgery in such emergency situations as uremia or local tumor symptoms. …
Percutaneous nephrostomy in the treatment of hydronephrosis during pregnancy: Our experience
1998
Hydronephrosis during pregnancy is commonly considered physiological due to compression of the ureters by the gravid uterus and by dilated ovarian veins. Only in symptomatic cases or secondary to obstruction is a urinary diversion required. Six cases of symptomatic hydronephrosis treated with percutaneous nephrostomy are reported. Tocolytic therapy was practised in order to avoid the risk of abortion.
