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…
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.
Ureterosciatic Hernia A Rare Cause of Pyonephrosis
1989
A female patient presented as an emergency case with pyonephrosis and septicemia as a result of ureterosciatic hernia. Septicemia was treated successfully by immediate percutaneous nephrostomy tubing. After complete disappearance of symptoms, the hernia was closed operatively. Topographic anatomy of ureterosciatic hernia is presented.
Percutaneous transrenal catheter retrieval.
1984
Percutaneous transrenal catheter retrieval was successfully performed in 6 of 7 patients using the percutaneous transrenal access. Three broken nephrostomy tubes and 3 indwelling splints were extracted. The instruments used were deflecting guide wire in 1, grasping forceps in 2, and Dormia stone basket in 3 instances. No complications were encountered.
Percutaneous Nephropyelostomy and Endo-Urological Manipulations
1982
After a long period of neglect (Goodwin et al. 1955), percutaneous nephropyelostomy (PNS) has gained general acceptance and replaced operative nephrostomy. In addition, the percutaneous approach has led to a number of new diagnostic and therapeutic procedures. The objective of this review is not to give a complete and detailed survey of PNS but rather to report on our technique and results with fine needle nephrostomy and various endo-urological manipulations.
Percutaneous Stone Manipulation
1981
Percutaneous stone manipulation by direct ultrasound disintegration, extraction or chemolysis was done on 34 patients. A total of 15 patients presented with an operatively established nephrostomy, while percutaneous nephrostomy and subsequent dilation of the nephrostomy channel were done in 19. The rate of complete stone clearance was 19 of 20 stones after percutaneous nephrostomy and 8 of 16 stones in the group with an operatively established nephrostomy. The primary goal, to remove obstructing pelvic stones, was achieved in all cases. There were no untoward side effects, such as back pressure damage owing to flushing of the collecting system during ultrasound disintegration, or persistent…
Extracorporeal shock wave lithotripsy of urinary calculi: experience in treatment of 3,278 patients using the Siemens Lithostar and Lithostar Plus.
1991
Between March 1986 and June 1989, 3,278 patients with upper urinary tract calculi were treated at our medical center with the Lithostar lithotriptor. The stones were located in the calices in 41.9% of the cases, renal pelvis in 25.7% and ureter in 32.4%. Perirenal hematoma was noted in 0.5% of the patients but this resolved spontaneously within a few days. Auxiliary procedures were performed in 37.3% of the cases, including Double-J stent and ureteral catheter in 26.8%, ureterorenoscopy in 2.1%, percutaneous nephrostomy in 1.6%, Zeiss loop in 4.3% and percutaneous nephrolithotripsy in 3.5%. Of the treatments 83.1% were performed without general or regional anesthesia. Followup after 3 month…
