Summary
Internal urinary drainage for pregnancy hydronephrosis showed limited success, with less than half of patients achieving sufficient drainage. The procedure also had a high complication rate, necessitating careful consideration.
Area of Science:
- Urology
- Obstetrics & Gynecology
- Medical Devices
Background:
- Symptomatic hydronephrosis during pregnancy can cause significant discomfort and potential complications.
- Internal urinary drainage is a potential intervention for managing pregnancy-related hydronephrosis.
Purpose of the Study:
- To evaluate the efficacy and complication rates of internal urinary drainage using ureteral stents in pregnant women with symptomatic hydronephrosis.
Main Methods:
- Retrospective analysis of 14 pregnant women with symptomatic hydronephrosis.
- Retrograde stenting via cystoscopy was performed.
- Follow-up included weekly and biweekly examinations.
Main Results:
- Primary stenting was successful in 12 of 14 patients; 2 required ureteral orifice dilatation.
- Over 75% of patients experienced complications, including dysuria, urinary tract infections, pain, and catheter issues.
- Only 6 of 14 patients achieved long-term relief from urinary tract obstruction.
Conclusions:
- Internal drainage for pregnancy hydronephrosis using double-J stents has a high complication rate and limited long-term efficacy.
- Careful evaluation is required before considering internal drainage for complicated pregnancy hydronephrosis.
