Evi Comploj, Armin Pycha
Urinary tract infections should be suspected in every febrile infant until proven otherwise. While older children and adolescents mostly present with classical features such as dysuria, flank pain and/or abdominal pain, secondary enuresis or pollakiuria, diagnosing infants or newborns, who are incapable of describing or pinpointing pain, can be much more challenging. As such, an infection with gradual and subtle onset may result in fulminant disease and emergency situations. In children with urinary tract infections and known mechanical or functional obstructions of the urinary tract, adequate drainage of the infected urinary tract may be necessary (e...

PURPOSE: To evaluate the effect of catheter-directed irreversible electroporation (IRE) on the integrity, patency, and function of the normal porcine ureter. MATERIALS AND METHODS: A catheter-mounted electrode was used to perform fluoroscopy-guided IRE in 8 healthy pigs. Two unilateral ablations (90 pulses at 2,000 V, 100 μs) were performed in each animal in the proximal and distal ureter. Serum creatinine measurements and contrast-enhanced computed tomography imaging were performed at 1, 7, 14, 21, and 28 days after IRE, and findings were compared with baseline values by Student t test...

In mammals, insulin primarily lowers plasma glucose (PGlu) by increasing its uptake into tissues. Studies have also shown that insulin lowers PGlu in mammals by modulating glomerular filtration rate (GFR). Birds have naturally high PGlu and, although insulin administration significantly decreases glucose concentrations, birds are resistant to insulin-mediated glucose uptake into tissues. Since prior work has not examined the effects of insulin on GFR in birds, the purpose of the present study was to assess whether insulin can augment renal glucose excretion and thereby lower PGlu...

The management of ventriculoperitoneal (VP) shunt failure is a common problem in neurosurgical practice. On occasion, extraperitoneal sites for CSF diversion are required when shunting to the peritoneal cavity has failed after multiple attempts. The authors report a novel minimally invasive procedure allowing cannulation of the ureter for the purpose of ventriculo-ureteral (VU) shunting. Sixteen years prior to presentation, this 46-year-old woman had contracted tuberculous meningitis and had chronic hydrocephalus, with multiple distal shunt failures in recent months...

Impacted stones frequently cause changes in the ureter, including edema of the ureteral wall, stone embedding in the ureteral mucosa or ureteral bending, which often preclude spontaneous passing of the stone and increase the risk of complications during surgery. When stone impaction is suspected preoperatively, management should be adapted accordingly. However, surgical treatment strategies remain controversial in pediatric patients because of the scarcity of cases reported. We describe the case of a 2-year-old girl with a right impacted ureteral stone who presented with gross hematuria and pyuria, but no metabolic risk factors or hematological abnormalities...

BACKGROUND: Ureteral injuries during colorectal surgery are a rare event, ranging in the literature from 0.28-7.6%. Debate surrounds the use of prophylactic lighted ureteral stents to help protect the ureter during laparoscopic surgery. It has been suggested that they help to identify injuries but do not prevent them. The authors look to challenge this. METHODS: Over 66 months, every laparoscopic or colectomy involving ureteral stents was recorded. Researchers documented any injury to the ureter intraoperatively...

Spinal cord injury (SCI) may lead to urinary system disturbances. Patients with SCI usually have neurogenic bladder, and treatment optionss for this condition include clean intermittent catheterization and a permanent indwelling urethral or suprapubic catheter. Complications of catheterization include urinary tract infection, calculi, urinary tract injury, bladder contraction, bladder spasm, renal dysfunction, bladder cancer, and so forth. To the best of our knowledge, ureteral rupture is an unusual complication of catheterization, and ureteral rupture has been rarely reported in SCI patients...

This protocol describes the generation of bladder tumors in female C57BL/6J mice using the murine bladder cancer cell line MB49, which has been modified to secrete human Prostate Specific Antigen (PSA), and the procedure for the confirmation of tumor implantation. In brief, mice are anesthetized using injectable drugs and are made to lay in the dorsal position. Urine is vacated from the bladder and 50 µL of poly-L-lysine (PLL) is slowly instilled at a rate of 10 µL/20 s using a 24 G IV catheter. It is left in the bladder for 20 min by stoppering the catheter...

This study was proposed to compare the clinical effectiveness of mini-tract percutaneous nephrolithotomy (MPCNL) with standard-tract percutaneous nephrolithotomy (SPCNL) and verify whether MPCNL is associated with both higher renal pelvic pressure (RPP) and incidence of postoperative fever. A total of 228 patients with kidney stone were randomly allocated to the MPCNL group (n=114) and SPCNL group (n=114). Both intraoperative and postoperative indexes along with the incidence of complications were compared between the two treatment groups...
