In 21 (44.6%) of the catheterized patients who had infected urine, UTI was eradicated after stent insertion. However, after insertion of the stent, UTI developed in only 40.9% of the patients with sterile urine. After insertion of the catheter, UTI developed in 79.4% of the patients who originally had sterile urine. Scanning electron microscopy (SEM) of the proximal and distal pieces of the stents removed from five patients with and five patients without UTI was carried out in a search for predisposing changes on the surfaces. ![]() Infection was assessed 1 month after placement of the devices. The SAS relative-risk test was used to compare the risks of UTI in 76 patients with temporary urethral stents, 60 patients with BOO who had never been catheterized nor stented, and 34 patients with a permanent indwelling urethral catheter (PIUC). To determine the efficacy of intraurethral metal stents in preventing or eradicating urinary-tract infections (UTI) during the management of bladder outlet obstruction (BOO) by comparing the frequency and nature of the infections with indwelling-catheter-associated UTI. Using catheters with inflating balloons can cause rapid increases in tension in the ureter, and related complications.Ĭomparison of nitinol urethral stent infections with indwelling catheter-associated urinary-tract infections.Įgilmez, Tulga Aridogan, I Atilla Yachia, Daniel Hassin, David Although placing an indwelling urethral catheter is a relatively safe procedure, complications can occur, particularly in patients with ureterovesical anomalies, such as high-grade VUR or an ectopic ureter. In one patient with VUR, intraparenchymal fluid leakage and transient hematuria occurred due to the rapid tension increase following the fast injection of contrast with liquid to one ureter. In this group, the catheter passed into the ureter because of the enlarged ureterovesical junction. The remaining three patients had grade 3 or 4 VUR. Three patients in this group with ectopic ureters were followed due a misdiagnosis of VUR. Cystoscopic examination found ectopic ureteral openings in six patients: at the bladder neck in four and just below the bladder trigone in two. The urethral catheter was in the left ureter in four patients and in the right ureter in five patients. In nine cases (five females, four males), a misdirected urethral catheter was discovered in one of the ureters. Size 6-10 Fr indwelling urethral catheters were used, depending on the patient's age and gender. In all, 1850 vesicograms were performed (746 males, 1104 females age 1 week to 14 years, mean age 3.8 years) using standard radiological techniques. Foley catheters with inflating balloons were used to obtain the vesicograms. From our computerized urology records over an 18-year period from January 1995 to May 2013, we retrospectively identified nine cases of 1850 vesicograms that had misdirection of a urethral catheter placed in a ureter. We report misdiagnosed or related complications due to indwelling urethral catheters unintentionally placed in the ureter. This requires urethral catheterization with transurethral replacement. Çelebi, Süleyman Sander, Serdar Kuzdan, Özgür Özaydın, Seyithan Güvenç, Ãœnal Yavuz, Sevgi Kıyak, Aysel Demirali, OyhanĬhildren commonly undergo vesicograms for diagnosing vesicoureteral reflux (VUR). Misdiagnoses caused by use of indwelling urethral catheters in children with ureterovesical junction anomalies. We describe the case of experitoneal bladder perforation successfully treated by urethral drainage. ![]() In most cases, laparotomy and suprapubic cystostomy are performed. Three weeks after the indwelling urethral catheter had been placed, the perforation was closed. Computed tomography and cystogram revealed experitoneal bladder perforation due to indwelling catheter. A 85-year-old man with an indwelling urethral catheter presented severe hematuria, abdominal pain with rebound tenderness and muscular tension over the suprapubic area after the exchange of the urethral catheter. Perforation of the bladder related to long-term indwelling urethral catheter is a rare and serious complication.
