Urinary Symptoms in Endometriosis — Bladder and Ureteric Disease

Urinary symptoms in endometriosis range from common irritative symptoms (cyclical frequency, urgency) to serious silent ureteric obstruction. This page covers bladder and ureteric endometriosis recognition and management.

1. Cyclical urinary symptoms

Cyclical dysuria, frequency, urgency tied to menstruation. Recurrent cystitis-like symptoms with negative urine cultures. Bladder pain during periods. Cyclical haematuria (highly suggestive but uncommon). Urinary retention episodes during menstruation. Pattern timed to cycle is the key feature.

2. Bladder endometriosis

Most common urinary endometriosis. Lesion on bladder wall, typically posterior/dome. Symptoms — cyclical urgency, frequency, dysuria, haematuria during periods. Diagnosis — expert ultrasound, MRI, cystoscopy in selected cases. Treatment — hormonal suppression often effective for symptomatic relief, surgical excision for refractory cases.

3. Ureteric endometriosis

Less common but more serious. Lesion at distal ureter, often near uterosacral region. Can cause silent ureteric obstruction with hydronephrosis. Renal damage if undiagnosed long-term. Cyclical flank pain possible. Often diagnosed incidentally on imaging or during endometriosis surgery. Renal function assessment essential.

4. Silent hydronephrosis — the danger

Up to 30 percent of women with deep infiltrating endometriosis have asymptomatic ureteric involvement with hydronephrosis. Renal function declines silently. Patients may have no urinary symptoms. Imaging surveillance important in moderate-severe endometriosis. Early intervention preserves renal function.

5. Diagnostic approach

Cyclical urinary symptoms — expert pelvic ultrasound with bladder evaluation, MRI for deep disease assessment. Suspected hydronephrosis — renal ultrasound, MR urography. Cystoscopy for bladder lesions in selected cases. Urine cytology, urine culture to rule out other causes. Renal function tests.

6. Medical management

Hormonal suppression effective for symptomatic bladder endometriosis. Continuous COCP, dienogest, Mirena, GnRH agonists/antagonists. Generally first-line for symptomatic but non-obstructive disease. Less effective for established hydronephrosis (anatomic intervention needed).

7. Surgical management

Bladder lesions — laparoscopic excision (partial cystectomy in significant cases). Watertight closure. 3D Karl Storz precision. Ureteric involvement — ureterolysis for compressive disease, segmental resection for transmural lesions, ureteric reimplantation in selected cases. Multidisciplinary with urology team.

8. Long-term monitoring

Annual renal ultrasound in patients with known urinary endometriosis or moderate-severe deep disease. Renal function monitoring. Hormonal management maintenance. Surveillance for new symptoms suggesting recurrence. Prompt evaluation of any new urinary symptoms or back pain.
