My clinical approach
Bladder diverticula are not simply an “anatomical curiosity.” When they cause recurrent infections, urinary retention, or stone formation — and especially when malignancy cannot be excluded — surgical removal is necessary. The 3D laparoscopic approach gives me the precision to work in an anatomically complex area (near the ureters, bladder neck) with minimal risk and rapid recovery for the patient.
3D laparoscopy for bladder diverticulectomy offers the advantages of minimally invasive surgery with the tactile perception and depth of vision of open surgery.
What is a bladder diverticulum?
A bladder diverticulum is a herniation or outpouching that forms when the bladder mucosa protrudes through a weak point in the detrusor muscle. Diverticula consist only of mucosa (without muscle wall) and therefore cannot contract. This means urine stagnates inside them — creating conditions for:
Causes and complications
Benign Prostatic Hyperplasia (BPH)
Chronic outlet obstruction increases intravesical pressure, progressively weakening the bladder wall.
Neurogenic bladder
Dysfunction of bladder muscle coordination leads to chronically elevated pressure.
Congenital
Hutch diverticula in children — located adjacent to the ureteral orifice.
Urethral stricture
Significant obstruction causes pressure-related diverticulum formation.
When is surgery indicated?
Pre-operative preparation
Imaging assessment
Bladder ultrasound, CT urography for size/position/ureteral relationship assessment.
Cystoscopy
Cystoscopy to exclude cancer within the diverticulum — mandatory before elective surgery.
Pre-operative tests
Full blood count, biochemistry, coagulation, ECG, anaesthesiologist assessment.
Ureteral stent
If the diverticulum is near the ureteral orifice, a DJ stent is placed before or at the start of surgery.
How the procedure is performed
Recovery and hospitalisation
Catheter
5–7 days (to allow bladder closure to heal). Cystography performed before removal to confirm watertight closure.
Hospital stay
2–4 days. Pain managed with standard analgesics — port incisions cause minimal discomfort.
At home
Increased fluid intake, avoid physical strain, no swimming for 4 weeks.
Return to work
Desk work ~2 weeks. Physical work 4–6 weeks.
Contact your urologist immediately if:
- Fever > 38.5°C
- Haematuria with clots or catheter obstruction
- Abdominal pain or abdominal distension
- Absence of urine output
Advantages vs open surgery
3D high-resolution imaging
Enhanced depth perception in a narrow anatomical space
Minimal blood loss
Electrosurgical haemostasis with minimal trauma
Shorter hospitalisation
2–4 days vs 5–7 days for open surgery
Faster recovery
Return to work 2 weeks vs 4–6 weeks
Small incisions
3–4 ports of 5–12 mm — minimal cosmetic impact
Fewer wound complications
Significantly reduced infection and hernia risk
Possible complications
Urine leakage (urinary fistula)
Rare — managed conservatively with extended catheterisation.
Ureteral injury
Very rare with DJ stent placement. Requires endoscopic or surgical repair.
Haematoma or bleeding
Managed conservatively in most cases.
Urinary tract infection
Antibiotic prophylaxis minimises risk.
Port hernia
Rare — 12 mm ports are sutured closed.
Frequently Asked Questions (FAQ)
What is a bladder diverticulum?
A bladder diverticulum is an outpouching of the bladder mucosa through a weak point in the bladder wall. It can be congenital or acquired (due to chronic outlet obstruction, e.g. BPH). Diverticula do not contract, leading to urinary stasis, recurrent infections, stone formation, and in some cases cancer.
Is laparoscopic surgery safe?
Yes. The laparoscopic approach for bladder diverticulectomy is performed by trained surgeons. Blood loss is minimal, hospital stay shorter, and cosmetic result superior compared to open surgery. 3D visualisation enhances surgical precision.
Why is a ureteral stent placed?
When the diverticulum is located near the ureteral orifice, a ureteral stent (DJ catheter) is inserted before surgery to facilitate identification of the ureter and prevent inadvertent injury during dissection.
How long is the catheter left in after surgery?
Usually 5–7 days. In complex cases or when the ureter was involved, the catheter may remain longer to ensure complete healing of the bladder closure.
Can the diverticulum recur after surgery?
Recurrence after complete surgical resection is very rare. However, if the underlying cause (e.g. BPH) is not treated, other diverticula or urological complications may develop.
How long does recovery take?
Typically 2–4 weeks for full recovery. Light activities may resume after catheter removal (5–7 days). Return to desk work: ~2 weeks. Physical work: 4–6 weeks.

If you have been diagnosed with a bladder diverticulum or experience recurrent UTIs and urinary problems, a specialist urology assessment will determine whether surgical treatment is indicated.
