OBJECTIVE The objective was to determine the incidence of bladder stones in patients with spinal cord injury (SCI) and to assess if catheter encrustation or positive urinary culture of Proteus mirabilis is predictive of bladder stones. BACKGROUND Bladder stones are common urological complication in those with SCI managed with indwelling urinary catheter. Detection and removal of bladder stone...

OBJECTIVE To test the performance and acceptability of an early warning sensor to predict encrustation and blockage of long-term indwelling urinary catheters. PATIENTS AND METHODS In all, 17 long-term indwelling catheter users, 15 'blockers' and two 'non-blockers' (controls) were recruited; 11 participants were followed prospectively until catheter change, three withdrew early and three did n...

Patients who failed a catheter-free trial after acute urinary retention and one week of full dose alpha-blocker and 5-alpha-reductase inhibitor were offered Diethylstilbestrol 1 mg plus Aspirin 100 mg over 4 weeks. Prostate volume, age, serum creatinine, and initial retention drained urine volume were recorded. After excluding cardiovascular morbidity (n = 7), upper urinary tract dilation (n = ...

INTRODUCTION Spinal cord injury patients are at risk for developing unusual complications such as autonomic dysreflexia while changing suprapubic cystostomy. We report a male patient with spina bifida in whom the Foley catheter was placed in the urethra during change of suprapubic cystostomy with serious consequences. CASE PRESENTATION A male patient, born in 1972 with spina bifida and parapl...

PURPOSE The effect of replacing the indwelling catheter of patients suspected of having a urinary tract infection (UTI) before collecting a urine sample on the number of organisms isolated in cultures and on drug and microbiology laboratory costs was studied. METHODS Data were collected for all patients hospitalized in two spinal cord injury (SCI) units between October 2001 and March 2002 who...

A 44-year-old man with Down’s syndrome and neurogenic bladder which required a suprapubic catheter presented with fever and change in his urine color for one day. Physical examination revealed a temperature of 38.3°C, blood pressure of 60/30 mmHg, pulse rate of 120/min and urine with purple discoloration in the urine catheter and bag (Figure 1). A urine dipstick test indicated the presence of l...

OBJECTIVE To determine the effectiveness of a non-return catheter valve vs. the standard urine bag for prevention of catheter-associated urinary tract infections (CAUTI) in critically ill patients. MATERIAL AND METHOD This was a pilot, randomized, stratified, open-label controlled trial (ClinicalTrials.gov, number NCT01963013). Ninety-six critically illpatients requiring indwelling urinary ca...

A 58-year-old paraplegic male, with long-term indwelling urethral catheter, developed catheter block. The catheter was changed, but blood-stained urine was drained intermittently. A long segment of the catheter was seen lying outside his penis, which indicated that the balloon of Foley catheter had been inflated in urethra. The misplaced catheter was removed and a new catheter was inserted corr...

OBJECTIVES To examine (i) the effect of triclosan on the formation of catheter biofilms by urinary tract pathogens and (ii) the diffusion of triclosan through the retention balloons of urinary catheters. METHODS Models of the catheterized bladder were infected with eight different urinary tract pathogens and the effect of triclosan on biofilm formation was assessed by determining the numbers ...

A 50-year-old man was admitted with a complicated pneumonia. During his long-term inpatient stay, a plastic urinary catheter was positioned. A month after admission the patient’s urine became purple (Picture 1). The patient was apyretic and did not have lower urinary tract symptoms but was constipated. Urinalysis revealed pH 7.8, leucocyturia and negative nitrites. Urine culture isolated Proteu...
