“…Also, there was a statistically significant difference depending on dwell time and comorbidi-ties; the diabetics and the patients with dwell time in excess of 90 days had significantly more positive urine cultures (6.8% vs. 28.6%, p value 0.01), as anticipated by previous published data [14] Stents left in situ more than 90 days have more than 9 times the chance of encrustations compared to their counterparts dwelling less than 30 days (76.3% vs. 8.5%).…”

“…Similarly, Kehinde et al [12] showed that the duration of J stent retention affects the rate of positivity of urinary cultures and J stent colonization, with a rate of 28.6 and 64.9%, respectively, with a stent indwelling time of 191 days; moreover, this author reports a bacteriuria rate in patients with no systemic disease that was significantly lower than in patients with diabetes mellitus, chronic renal failure and diabetic nephropathy.…”

Objectives: To analyze the early and late complications of indwelling ureteral stents in a series of 146 patients with nephroureteral lithiasis. Materials and Methods: 146 patients with obstructing nephrolitiasis were treated for urinary diversion with double pigtail ureteral stent before extracorporeal shock-wave lithotripsy (ESWL) and following ureterorenoscopic treatment of lithiasis. All patients were scheduled for stent removal or replacement at specific 3-month intervals until stone-free status was achieved. Results: Early complications during the first 4 weeks after stent insertion were stent discomfort (37.6%), irritative bladder symptoms (18.8%), hematuria (18.1%), bacteriuria (15.2%), fever >104F (12.3%) and flank pain (25.3%); late complications included hydronephrosis (5.7%), and stent migration (9.5%), encrustation (21.6%), fragmentation (1.9%) and breakage (1.3%). Conclusions: Ureteral stents have proven to be an invaluable tool for endourologists. Morbidity is minimal for up to three months but longer indwelling times are associated with an increasing frequency of incrustation, infections, secondary stone formation and obstruction of the stented tract.

“…Kehinde et al [13] showed that the risk of bacteriuria and colonisation of the J stent tip is enhanced significantly by a longer duration of stent retention, female gender, and systemic diseases such as diabetes mellitus, chronic renal failure and diabetic nephropathy and concluded that these categories of patients should undergo shorter stent retention, antimicrobial prophylaxis, and careful follow-up to minimise infectious complications. Coskun et al [14] stressed that early removal of the stent, 2 weeks after renal transplantation, decreased the rate of urinary tract infections.…”

BACKGROUND Stents and catheters are widely used in Urology. In this study, we identified the incidence of DJ stent bacterial colonisation and its correlation with bacteriuria frequency. MATERIALS AND METHODSBetween January 2015 and June 2016, 170 patients (17 to 72 years old) who underwent DJ stenting were enrolled in the study. Surgeries prior to stenting included PCNL, URS, Pyeloplasty, Pyelolithotomy and Ureterolithotomy. Prior to stenting, sterile urine samples were obtained, and urinary cultures were performed upon removal of the DJ stents along with stent culture. Eighty-three stents were inserted into the right ureter and eighty-seven into the left ureter of the patients. RESULTSCultures showed bacterial colonisation in 27 (16%) cases. There was no significant association between positive stent culture and patient age, sex or stent laterality. The rate of colonisation was 2.2%, 2.9%, and 25% when indwelling time was less than 4 weeks, 4-6 weeks, and more than 6 weeks, respectively. In the present study, the rate of infection associated with a DJ stent and urinary infection was not very high. However, bacterial colonisation increases significantly with indwelling time of the stent and sterile culture of urine does not rule out colonisation of the stent. CONCLUSIONBacteriological investigation showed very low rates of colonisation within 6 weeks after the insertion of stents, indicating that ureteral stents can be used safely within that time period. Bacterial colonisation is associated with increased chances of bacteriuria frequency. KEYWORDS BACKGROUNDAs the field of Endourology has developed, a great variety of foreign bodies have been designed, and with the increasing number of biomaterial devices used in Urology, biofilm formation and device infection are issues of growing importance. [1] In the present study, the frequency of colonisation on double J (DJ) stents and stent-associated bacteriuria was investigated. We aimed to compare the relationship between the colonisation of the bladder urine and that on the DJ stents that have been inserted for various reasons. We investigated the importance of indwelling time for infection and antimicrobial susceptibility pattern of isolates in order to establish data on the aetiologic agents of Colonised stents and evaluate the significance of urinary cultures for the identification of colonising microorganisms.
