Abstract

PURPOSE: Temporary drainage of the upper urinary tract by use of internal ureteral stents is a common procedure that is often associated with a variety of symptoms. The role of intravesical stent position in associated morbidity is controversial.
MATERIALS AND METHODS: The German version of the ureteral stent symptom questionnaire (USSQ) was completed by 73 patients with an indwelling ureteral stent the day before stent removal. Intravesical stent position was classified into 3 categories by x-ray before stent removal. The influence of intravesical stent position on USSQ score was analyzed, including subscores and single items.
RESULTS: Intravesical stent position showed no significant influence on associated morbidity. The median USSQ total score in all patients was 77.5 (range, 30-147). Patients with ipsilateral stents (69.0; range, 30-122) tended to have lower total scores than did those with tangential (86.5; range, 30-122) or contralateral (77.0; range, 31-147) stents, but the differences were not statistically significant (p=0.35). The USSQ subscores for urinary symptoms (p=0.80), body pain (p=0.80), general health (p=0.16), work performance (p=0.07), additional problems (p=0.81), and all of the USSQ single items of interest in the context of stent length also did not differ significantly between the three groups.
CONCLUSIONS: Intravesical stent position did not significantly influence associated morbidity in our study. An appropriate stent length should be chosen to avoid dislocation. However, complex calculations of optimum stent length, time-consuming manipulations, and costly stock holding of various stent sizes to obtain the perfect stent position do not seem worthwhile.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
