This case report describes a woman who experienced intermittent urinary retention. The cause was a large hydrosalpinx, a fluid-filled fallopian tube, which pushed the uterus forward and compressed the bladder. A bladder scan showed a high post-void residual, but this was misleading due to the hydrosalpinx. After surgery to remove the hydrosalpinx, the patient's symptoms disappeared. The authors suggest that gynecological conditions like hydrosalpinx should be considered when diagnosing urinary retention, especially if imaging shows pelvic masses.
Area of Science:
- Gynecology and Obstetrics
- Urology
- Clinical Case Studies
Background:
Acute urinary retention is uncommon in female patients. It is typically linked to neurological or obstructive causes. However, gynecological conditions can also play a role. Prior research has shown that pelvic masses may compress the bladder or urethra. This gap motivated further investigation into non-traditional causes. No prior work had resolved the link between hydrosalpinx and urinary retention. The literature lacks detailed case reports on this association. This paper contributes a rare clinical scenario. It expands understanding of how gynecological anomalies may affect urinary function.
Purpose Of The Study:
This case aimed to document a rare cause of intermittent urinary retention. The patient presented with symptoms not typically seen in gynecological disorders. The goal was to identify the anatomical mechanism behind the retention. The researchers sought to clarify the role of hydrosalpinx in this condition. They also wanted to highlight diagnostic challenges. The study aimed to prevent misdiagnosis due to misleading bladder scans. The motivation was to improve clinical awareness of this association. The authors hoped to guide future diagnostic approaches.
Main Methods:
The study involved a single patient with a history of intermittent retention. Imaging was used to assess pelvic anatomy and bladder function. A bladder scan was performed to measure post-void residual volume. The scan showed an abnormally high residual, raising suspicion of obstruction. The patient underwent a pelvic ultrasound to evaluate for masses. The ultrasound revealed a large hydrosalpinx compressing the bladder. Surgical intervention was planned to remove the hydrosalpinx. The patient’s symptoms were monitored post-operatively.
Main Results:
The patient experienced intermittent urinary retention and elevated post-void residual. The ultrasound identified a large hydrosalpinx displacing the uterus anteriorly. The bladder scan falsely suggested a high residual due to the hydrosalpinx. Following salpingectomy, the patient’s symptoms resolved completely. The post-void residual normalized after the procedure. No further episodes of retention were reported. The anatomical compression was confirmed as the cause. The results suggest that hydrosalpinx can mimic urinary obstruction.
Conclusions:
The authors propose that hydrosalpinx may cause urinary retention through mechanical compression. The case highlights the importance of imaging in diagnosing pelvic causes. The bladder scan may give misleading results in the presence of a hydrosalpinx. The resolution of symptoms after surgery supports this mechanism. The findings suggest that gynecological causes should be considered in retention cases. The study does not claim this is a common cause. The authors emphasize the need for a multidisciplinary approach. They recommend further case reports to confirm this association.
Frequently Asked Questions
The authors propose that a large hydrosalpinx may cause urinary retention by compressing the bladder.
The patient underwent a bladder scan and pelvic ultrasound to identify the hydrosalpinx.
The hydrosalpinx may have caused a falsely elevated post-void residual on the bladder scan.
Imaging confirmed the presence of a large hydrosalpinx displacing the uterus and cervix.
The patient's symptoms resolved after salpingectomy, and the post-void residual normalized.
The authors recommend considering gynecological causes in cases of unexplained urinary retention.
