Reconstructive urology: rebuilding the urinary passage.
When part of the urinary tract is narrowed, damaged or underdeveloped, reconstructive procedures repair or rebuild it — restoring normal flow and protecting kidney function.
What is reconstructive urology?
Most urology removes something — a stone, an enlarged prostate. Reconstructive urology does the opposite: it repairs and rebuilds. It is called for when a passage is too narrow (a stricture), a junction is blocked (PUJ obstruction), or a bladder has become too small or high-pressure to store urine safely. These are planned, precise operations — often done with keyhole or robotic techniques.
Urethral stricture management — VIU and BMG urethroplasty.
A urethral stricture is scar tissue narrowing the urine passage, causing a progressively weaker stream. Two main procedures restore flow:
- VIU (visual internal urethrotomy) — through a telescope, the tight ring of scar is opened with a fine cut. Quick and effective for short strictures
- BMG urethroplasty — for longer or recurrent strictures, the narrowed segment is reconstructed using a small graft from the inner cheek (buccal mucosa). Among the most durable results of any stricture treatment

Pyeloplasty — for PUJ obstruction.
PUJ (pelvi-ureteric junction) obstruction is a narrowing where the kidney meets the ureter. Urine drains poorly, the kidney stretches (hydronephrosis), and over time its function suffers. It is often found on an ultrasound — sometimes even before birth, sometimes after flank pain or infection in adulthood.
Pyeloplasty corrects it: the narrowed segment is removed and the junction rebuilt with a wide, smooth opening. It is usually performed by keyhole (laparoscopic) or robotic surgery — small cuts, short hospital stay, and quick recovery — and it protects the kidney from further damage.
Augmentation cystoplasty — enlarging a small, high-pressure bladder.
Some bladders — after long-standing obstruction, neurological disease or certain infections — become small, stiff and high-pressure. Left alone, the pressure travels up and damages the kidneys. When medicines are no longer enough, augmentation cystoplasty enlarges the bladder using a carefully prepared segment of intestine, lowering the pressure and restoring safe storage capacity.
It is a considered, planned operation offered after thorough evaluation (including bladder pressure studies), and patients are guided closely before and after — including learning clean intermittent catheterisation where needed.
How the need for reconstruction is assessed.
- Urine flow test and ultrasound — the first, simple measures of flow and drainage
- X-ray studies of the urethra or CT scans — map exactly where and how long a narrowing is
- Renal scans — show how well each kidney drains and functions before pyeloplasty
- Bladder pressure studies (urodynamics) — essential before considering cystoplasty
These tests make the plan precise — reconstructive surgery is never guesswork.
Recovery — what to expect.
- VIU — short procedure; catheter for a few days; quick return to routine
- BMG urethroplasty — a few days in hospital; catheter for about 2–3 weeks while the graft heals; cheek discomfort settles in days
- Pyeloplasty (keyhole/robotic) — usually 2–3 days in hospital; an internal stent stays for a few weeks and is removed in a short outpatient visit
- Augmentation cystoplasty — a longer recovery with close follow-up; your team teaches you bladder care step by step

What is reconstructive urology?
Reconstructive urology is the branch of urology that repairs or rebuilds parts of the urinary tract when they are narrowed, damaged or underdeveloped — for example urethral stricture repair (urethroplasty), pyeloplasty for kidney drainage blockage, and augmentation cystoplasty for a small, high-pressure bladder.
What is pyeloplasty?
Pyeloplasty is an operation that corrects PUJ obstruction — a narrowing where the kidney meets the ureter that traps urine and stretches the kidney. The narrowed segment is removed and the passage rebuilt, usually by keyhole or robotic surgery, protecting the kidney from further damage.
What is augmentation cystoplasty?
Augmentation cystoplasty is an operation that enlarges a small, overactive or high-pressure bladder using a segment of intestine. It protects the kidneys from pressure damage and improves bladder capacity in selected patients whose bladders no longer respond to medicines.
Is reconstructive urology done by keyhole or robotic surgery?
Many reconstructive procedures — such as pyeloplasty — are done by laparoscopic (keyhole) or robotic techniques, which mean smaller cuts, less pain and faster recovery. Urethroplasty is performed through the natural passage or a small incision. The approach is chosen after reviewing your scans and health.
How successful is urethroplasty for a urethral stricture?
For suitable strictures, BMG urethroplasty has among the most durable results of any stricture treatment, with low recurrence rates. Follow-up with a simple urine flow test catches any recurrence early.
