Introduction
ureteral stents are used in managing various urological conditions. When these stents are left indwelling for a prolonged time, it results in complications like stent migration, fragmentation, and encrustation. The aim of this retrospective observational study is to analyse the incidence, risk factors, and morbidity associated with retained ureteral stents.
Methods
the retained/forgotten ureteral stents were defined as the stents with an indwelling period of more than six months. The records of all such patients from January 2010 to January 2020 were retrospectively reviewed. The primary reason for the placement of a stent, total indwelling time, the reason for prolonged indwelling time, and part(s) of the stent encrusted were retrospectively reviewed. Single/multistage endourological procedures were used to make the patients remove the retained stents and stone free. The type, number of procedures, and total number of sessions needed were noted.
Results
data of 114 patients was reviewed retrospectively. Most patients presented with abdominal pain (62 patients, 54.4%), and dysuria (41 patients, 35.1%). An average of 1.7 sessions (range 1-4) were needed to make the patients’ stent and stone free. During these sessions, single/multiple procedures (endoscopic/open/combined) were performed. Nine patients (7.9%) had permanent loss of renal unit function and who needed a nephrectomy. Poor compliance (45.6%), unawareness (35.1%), and misconception that the stent would last a lifetime (12.3%), were the most common reasons for retained ureteral stents. The incidence rate of retained stents fell from 1.1% to 0.5% after the “three steps” prevention check method was in-cooperated to ensure timely follow-up of the patients.
Conclusion
retained ureteral stents are a significant source of morbidity, which is avoidable by ensuring timely removal. Sincere efforts should be made to make patients aware of an indwelling foreign body. Prevention is the best strategy.
Objective: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is characterized by pelvic pain and voiding symptoms, the management of which is challenging. The present study was designed to assess the efficacy of biofeedback and pelvic-floor relaxation treatment for CP/CPPS. Methods: A total of 84 patients diagnosed with CP/CPPS were randomly assigned to one of the two groups: conventional therapy (group A) and pelvic-floor muscle relaxation and biofeedback (group B). The Biofeedback and Electrical Stimulation apparatus was used for pelvic-floor muscle electrical stimulation and relaxation with biofeedback. National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores were evaluated at the start of therapy, after 3 months of treatment and at 6 months (3 months after last treatment received). Results: At 3 months, patients in both groups had a significant decrease (improvement in symptoms) in NIH-CPSI scoring. However, at 6 months, only 19 (47.5%) patients in group A maintained a fall in NIH-CPSI score >6 compared with 37 (94.8%) patients in group B ( p<0.05). At 6 months, there was significant decrease in NIH-CPSI score in group B, whereas in group A, scores had increased (worsening of symptoms). Conclusions: Pelvic-floor muscle relaxation and biofeedback training is a safe and effective treatment for CP/CPPS with sustained efficacy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
