Outflow obstruction and bladder stones in Kelantan
Insights
Bladder stones in men are often linked to urinary outflow obstruction. However, this study found most men with bladder stones in Kelantan did not have obstruction, suggesting other causes are significant.
Area of Science:
- Urology
- Epidemiology
Background:
- Bladder stones in men are commonly attributed to urinary outflow obstruction.
- The specific etiological factors for bladder stones in Kelantan remain under investigation.
Purpose of the Study:
- To investigate the relationship between bladder stones and urinary outflow obstruction in men in Kelantan.
- To determine the incidence of procedures for outflow obstruction among men undergoing bladder stone removal.
Main Methods:
- Retrospective analysis of patient data.
- Examining the records of men who underwent bladder stone removal and procedures for urinary outflow obstruction.
Main Results:
- Only 31% of 154 men with bladder stones had undergone a procedure for outflow obstruction.
- A significant proportion of men (22%) who had prostatectomy also had bladder stones.
- This indicates that 69% of men with bladder stones lacked clinical evidence of obstruction.
Conclusions:
- Urinary outflow obstruction is not the sole cause of bladder stones in men in Kelantan.
- Other etiological factors likely play a crucial role in bladder stone formation in this region.
- Further research into alternative causes of bladder stones is warranted.
Abstract:
Bladder stones in men are thought to be almost exclusively due to outflow obstruction. We studied the incidence of operations for urinary outflow obstruction and bladder stone to establish the relationship between these two conditions in Kelantan. In only 48 (31%) of 154 men undergoing removal of bladder stones was a procedure for outflow obstruction performed. Thus the remaining 69% had no clinical obstruction to account for their stones. Bladder stones were more common in prostatectomy patients than expected (42/193: 22%). We suggest that other causes may be important in the aetiology of bladder stones in Kelantan.
