Ureteral stents are one of the most commonly used urologic devices with the purpose of establishing and maintaining ureteral patency. They are also associated with a number of complications including infection, migration, stent-related symptoms, and encrustation, leading to lithiasis. Prolonged stent dwell time is associated with a greater degree of these complications. We present the case of a 36-year-old man who presented with a severely encrusted ureteral stent that had been placed 12.5 years prior for an obstructive left-sided ureteral stone and was lost to follow-up. The patient underwent a combination of percutaneous nephrolithomy, cystolitholapaxy, and ureteroscopy to remove the stent and associated 1.7 cm renal pelvic stone and 4.1 cm bladder stone, necessitating two operative sittings to render him stone free.

“…Ureteral stents are an integral part of the treatment of different urological conditions such as nephrolithiasis, ureteral stricture, malignant obstruction, ureteral injury and healing [1, 2]. Retained ureteral stents (RUS) may cause infection, encrustation, and patient discomfort.…”

A new patient safety smartphone application for prevention of “forgotten” ureteral stents: results from a clinical pilot study in 194 patients

BackgroundApproximately 12% of all ureteral stents placed are retained or “forgotten.” Forgotten stents are associated with significant safety concerns as well as increased costs and legal issues. Retained ureteral stents (RUS) often occur due to lack of clinical follow-up, communication or language barriers, and economic concerns.MethodsWe describe a multiplatform application that facilitates data collection to prevent RUS. The “Stent Tracker” application can be installed on mobile devices and computers. The encrypted and password-protected information is accessible from any device and provides information about each procedure, stent placement and removal dates, as well as product description. This multicenter retrospective study included 194 patients who underwent stent placement between July and October 2015. Nominal data was tallied and ordinal data was divided into quartiles of 25, 50, and 75%.ResultsA total of 194 patients from three institutions underwent ureteral stent placement. Reasons for stent placement include 122 cases post ureteroscopy (63%), 8 cases post percutaneous nephrolithotomy (PCNL) (4%), 14 cases post extracorporeal shock wave lithotripsy (SWL) (7%), 18 cases of cancer-related ureteral obstruction (9%), 21 cases of hydronephrosis (11%), and 11 for other reasons (6%). Of these patients, only one patient was lost to follow-up (0.5%). On average, ureteral stents were removed within 14 days of placement (IQR: 8-26 days).ConclusionsThe “Stent Tracker” is a patient safety application that provides a secure and simplified interface, which can significantly reduce the incidence of RUS. Further developments could include automated notifications to patients and staff, color-coding, and integrated information with electronic patient charts.

“…However, it is associated with patient discomfort and a negative effect on quality of life (QoL) [4][5][6]. To decrease stent-related discomfort, several trials have been conducted to study the effect of pharmacological agents (Alpha-receptor blockers, M-receptor blockers, Chinese herb) and new stent materials on stent-related symptoms [7][8][9]. A reliable and valid measure of such patient experience is therefore becoming a more important assessment of clinical outcomes and would form the basis for the research and development of better treatment methods.…”

Objective: We validated the Chinese version of the Ureteral Stent Symptoms Questionnaire (USSQ) in patients with an indwelling ureteric stent. Patients and Methods: The English version of the USSQ was translated into Chinese using a multi-step process by 3 urologists and 2 independent translators. The Chinese version was validated by asking 50 patients with temporary unilateral ureteral stent to complete the questionnaire at weeks 1 and 4 after stent placement. Thirty healthy individuals without a ureteral stent were also asked to complete the Chinese USSQ once. The psychometric properties of the questionnaire were analyzed. Results: After revision of the initial 2 drafts after translation, back translation, and pilot testing, a final draft was developed that underwent field testing. Psychometric analyses revealed satisfactory internal consistencies and test-retest reliability for all domains except for sexual matters. Most USSQ domains showed moderate correlations with each other. It demonstrated satisfactory discriminant validity (sensitivity to change, p < 0.05) and test-retest reliability. Analysis of the domains of the sexual matters was limited because of the small proportion of the study population for whom it was applicable. Conclusion: The Chinese version of the USSQ is a reliable and valid instrument to evaluate symptoms and health-related quality of life in Chinese patients with ureteric stents.
