“…There are various methods described in literature as to how encrustations can be removed with minimal invasive techniques. These include extracorporeal shock wave lithotripsy (ESWL) [8], intraluminal pneumatic lithotripsy [9], and directly crushing the encrustations with a rigid cystoscope inserted through a suprapubic cystostomy tract [6]. However, in our patient, the encrustation was so large that any non-invasive technique would have been technically difficult.…”

Introduction: Indwelling urinary catheters cause a variety of complications including infections, pain and bleeding. Sometimes, the catheter becomes encrusted and blocked. Case Report: A 66-year-old male was presented with increasing suprapubic pain for about two months because of a poorly draining Foley catheter. Two years earlier, the patient had undergone a transurethral resection of the prostate (TURP) gland. He was given a Foley catheter and asked to follow-up in a week. He did not follow-up or change the catheter for two years. The catheter could not be removed. A computed tomography scan of the abdomen showed a large encrustation of 5.0x5.2x5.5 cm surrounding the Foley. The patient underwent open suprapubic cystostomy with intact retrieval of stone along with the catheter. Conclusion: Indwelling Foley catheters frequently become encrusted and may become difficulty to remove. The developments of giant encrustations are unusual. Such giant encrustations usually need surgery for removal.

“…The bacteria most commonly associated with the production of stones is Proteus mirabilis, although a wide variety of other organisms have been implicated [5]. Encrustations can occur either in the lumen of the catheter or outside of it [6].…”

“…In people, urinary implants are preferably removed as infection with urease-producing bacteria, biofilm and mineralization of the implants commonly occur. 23 – 25 Reduced encrustation has been reported with silicone catheters; however, recent veterinary research has shown a decreased prevalence of mineralization with polyurethane catheters (7.8%) in comparison to silicone catheters (17.5%). 1 Development of catheters resulting in less crystal adherence could help reduce encrustation.…”

Objectives The aim of this study was to evaluate the efficacy and tolerability of a 4% tetrasodium EDTA (tEDTA) infusion protocol in the subcutaneous ureteral bypass (SUB) devices of cats with intraluminal obstruction at a veterinary teaching hospital between July 2017 and April 2020. Methods This was a retrospective controlled study. Cats with an obstructed SUB device underwent a 4% tEDTA infusion protocol. Obstruction of the device was diagnosed based on renal pelvic dilation, dilatation of the ureter, mineralized material within the device (cystostomy or nephrostomy catheters) seen on ultrasound, the absence of visible bubbles within the renal pelvis and/or urinary bladder following ultrasound-guided flushing of the device with saline. Results A total of 16 tEDTA infusion protocols were performed in 14 cats. The infusion protocol was considered successful in 11/16 SUB devices (68.8%). Six devices (n = 6/11; 54.5%) had recurrence of obstruction with a median time of 87 days. One or more episodes of self-limiting pollakiuria and/or hematuria following infusion was seen in eight patients (n = 8/14; 57.1%). Conclusions and relevance Infusions of 4% tEDTA successfully relieved intraluminal obstruction in patients with occluded SUB devices; however, the recurrence of obstruction was common. Additional studies evaluating case selection and optimal protocols are warranted.

“…This is caused by urease-producing bacterial overgrowth leading to ammonia, alkaline urine and formation of calcium and magnesium phosphate crystals. 30 Progressive accumulation of these crystals within and on the catheter can eventually cause partial or complete blockage of the lumen, resulting in urinary retention and severe secondary complications.…”

Introduction:Catheter-associated urinary tract infections comprise a significant burden to the health care system and are of major concern for indwelling catheter use. Catheter coatings have been studied for their potential to reduce risk of infection. The purpose of this meta-analysis is to determine the efficacy of coated catheters across clinical studies in preventing these common nosocomial infections.Methods:Searches were conducted on PubMed Central® and ScienceDirect using the terms “catheter,” “urinary tract infection” and “coated” or “antimicrobial.” Articles included were prospective randomized clinical studies of coated (experimental) vs uncoated (control) catheters published in English between the years 2000 and 2020. Results from included studies were analyzed using Fisher’s exact test and conditional logistic regression.Results:Fifteen studies met the inclusion criteria. Tested urinary catheter coatings include silver, silver salt, nitrofurazone and metal-alloy. Conditional logistic regression (p <0.001) shows statistically significant negative association between coated catheter use and the incidence of catheter-associated urinary tract infections. The odds ratio of 0.80 and 95% confidence interval (0.74, 0.88) support protective effect of catheter coatings.Conclusions:Meta-analysis demonstrates a negative association of coated catheter and incidence of catheter-associated urinary tract infections, supporting that antimicrobial catheter coatings decreases incidence of infection across studies. Further clinical research is recommended to determine the potential for catheter coating adoption in clinical practice to reduce catheter-associated urinary tract infection risk and incidence.
