Features of the extraction of foreign bodies from the lower urinary tract

BACKGROUND:Foreign bodies introduced by patients into the bladder and urethra are relatively rare in clinical practice. As a result, there is insufficient information in the scientific literature regarding methods of extracting foreign bodies from the urinary tract. 
AIM:determination of the optimal methods for extracting foreign bodies from the urethra and bladder. 
MATERIALS AND METHODS:Foreign bodies of the lower urinary tract were removed in 21 patients: 15 (71.4%) men and 6 (28.6%) women. Foreign bodies were found in the urethra in 7 (33.3%) patients and in the bladder in 14 (66.7%) patients. Removal of foreign bodies from the urethra and bladder was performed endoscopically or during open surgery. 
RESULTS:Removal of stabbing, cutting and glass objects from the urinary tract in 9 patients was performed during open surgery. Foreign bodies with even smooth edges were removed in 12 patients under urethrocystoscopic control. At the same time, in two patients, coagulated suppositories were first fragmented in the bladder cavity, and then removed in parts. Cystolithotripsy was performed in one patient with a suppository inlaid with calculus before fragmentation. 
CONCLUSIONS:Foreign bodies with sharp edges or made of glass are safer to be removed from the lower urinary tract during open surgery. Foreign bodies with a smooth and even surface are optimally removed endoscopically. Long and bulky foreign objects that can be fragmented in the bladder cavity are best removed in parts. When foreign bodies are encrusted with large calculi, cystolithotripsy should be performed before their endoscopic extraction.
