Pyeloplasty - robotic reconstruction, first-attempt success.

Definitive reconstruction of a narrowed pelviureteric junction - most commonly robotic-assisted, dismembered Anderson-Hynes technique, by a consultant reconstructive urologist with a genuine PUJ practice.

The problem

Get it right first time - redo pyeloplasty is another operation.

Adult pyeloplasty is where volume matters most. First-time robotic success is above 95 percent in the right hands; redo work is measurably harder.

  • Choose the surgeon before the technology

    Robots do not fix bad anastomoses. A named consultant with a genuine pyeloplasty practice is what wins the case.

  • Do not settle for endopyelotomy in a crossing vessel

    If CT shows a crossing lower-pole vessel, endopyelotomy will fail. Dismembered pyeloplasty is the correct answer.

  • Renogram before, renogram after

    Function and drainage on MAG3 are the honest metrics. If nobody has requested a 3-month post-op renogram, ask why.

When it helps

When pyeloplasty is the right step.

The situations we see most, plus the one red flag that means A&E rather than a routine PUJ clinic.

  • Symptomatic PUJ obstruction

    Recurrent loin pain, especially after drinking a large volume of fluid (Dietl crisis), with an obstructed drainage curve on MAG3.

  • Deteriorating split kidney function

    Ipsilateral function under 40 percent or a drop of 5 percent or more between renograms - a hard indication.

  • Recurrent kidney stones from stasis

    Stones repeatedly forming in a poorly draining renal pelvis - treating the obstruction stops the loop.

  • Recurrent pyelonephritis from stasis

    Recurrent kidney infections that resolve only when the obstructing anatomy is corrected.

  • Failed endopyelotomy

    Restenosis after a prior endopyelotomy - reconstructive pyeloplasty is now the correct next step.

  • Crossing lower-pole vessel

    CT confirming a crossing vessel across the PUJ - endopyelotomy is unsuitable, dismembered pyeloplasty is definitive.

  • Congenital PUJ obstruction found in adulthood

    A previously silent congenital narrowing that presents in the 20s to 40s with pain, stone or infection.

  • Red flag: fever with an obstructed kidney

    Fever, flank pain and an obstructed system is an infected obstruction - this is A&E for urgent nephrostomy or stent, not a routine appointment.

Procedure options

Robotic, laparoscopic, open, endopyelotomy - anatomy decides.

What each option involves and where it sits best in a modern UK reconstructive urology pathway.

  • Robotic-assisted dismembered pyeloplasty

    The da Vinci system with wristed instruments and 3D vision. The dismembered Anderson-Hynes technique - excise the narrowing, reshape the pelvis, join it to healthy ureter. UK adult default.

  • Laparoscopic dismembered pyeloplasty

    Same operation without the robot. Steeper learning curve but comparable long-term success in expert hands. Reserved to units without a robotic programme.

  • Open dismembered pyeloplasty

    A flank incision. Reserved for redo cases, very complex anatomy, or when robotic is unavailable. Longer stay and slower recovery.

  • Endopyelotomy (holmium or cold-knife)

    An endoscopic incision through a short narrowing from inside the ureter. Suitable only for short segments with no crossing vessel and preserved function. Success 60 to 75 percent.

  • Antegrade vs retrograde endopyelotomy

    Antegrade via a percutaneous tract, retrograde via the ureter with a flexible scope. Retrograde is less morbid but limited to short strictures.

  • Ureterocalicostomy

    A salvage option for intrarenal pelvis or after failed pyeloplasty - the lower calyx is anastomosed directly to the ureter after amputating the lower pole.

  • Concomitant stone treatment

    Stones in the renal pelvis can be removed at the same sitting as pyeloplasty - flexible pyeloscopy or basketing during the reconstruction.

  • Buccal mucosa onlay pyeloplasty

    A niche technique in redo or long strictures - a graft of buccal mucosa augments the reconstruction. Available in a handful of UK reconstructive centres.

Safety and recovery

What to expect afterwards - honestly.

Pyeloplasty is a well-established operation. The things worth planning are the stent weeks, the 3-month renogram and long-term ultrasound surveillance.

  • GA and a urology ward bed

    Every approach is under general anaesthetic. One to two nights for robotic and laparoscopic, three to five for open.

  • Anastomotic leak

    Under 2 percent - usually managed conservatively with extended stent time. Percutaneous drainage occasionally needed.

  • Bleeding and vascular injury

    Bleeding significant enough to need transfusion is under 2 percent. Vascular injury to the crossing vessel is rare and usually repaired robotically.

  • Infection and pyelonephritis

    Wound infection is uncommon. Pyelonephritis in the stented period occurs in 2 to 5 percent - culture-guided antibiotics.

  • JJ stent symptoms

    Frequency, urgency and mild flank pain are common with the stent in place. They resolve within days of removal.

  • Stricture recurrence

    Under 5 percent for primary robotic pyeloplasty. Higher for redo cases (10 to 15 percent) and for endopyelotomy (25 to 40 percent).

  • Nephrectomy as a last resort

    Where function is already under 15 percent and pyeloplasty is unlikely to preserve the kidney, removal is sometimes the honest recommendation.

  • Port-site or incisional hernia

    Under 2 percent for laparoscopic and robotic; higher after open. Fascial closure at all ports helps.

  • Red flags after discharge

    Fever, worsening flank pain, spreading redness, heavy visible haematuria - same-day urology team or A&E, not a routine call.

Reading your operation note

Your pyeloplasty note in four parts. Read the last one first.

Whichever approach was used, the note the urologist sends you keeps to the same shape.

A quiet reminder

Reconstructive urology notes can read coldly - we translate them for you.

If you would like us to talk you through the operation note and 3-month renogram, just ask.

    Approach, side and stent

    Whether robotic, laparoscopic, open or endopyelotomy, side, and whether a JJ stent was placed antegrade during the operation.

  2. 02 Technique

    Findings, crossing vessel, reconstruction

    Intra-operative findings, whether a crossing vessel was transposed, and the anastomotic technique (Anderson-Hynes, YV plasty).

  3. 03 Findings

    Pelvis reduction and drainage test

    Whether the pelvis was reduced to a normal shape and how drainage looked when tested at the end of the case.

Frequently asked

Everything we get asked about pyeloplasty.

Quick answers on approach, stent, success, cost and recovery.

  • What is pyeloplasty and why is it done?

    Pyeloplasty is reconstructive surgery for pelviureteric junction (PUJ) obstruction - a narrowing where the renal pelvis meets the ureter that stops urine draining out of the kidney. Left untreated, it causes recurrent loin pain, stones, infections and progressive loss of kidney function. Pyeloplasty removes the narrowing and reshapes the pelvis so urine drains freely.

  • Robotic, laparoscopic, open or endopyelotomy - which is best?

    Robotic-assisted dismembered pyeloplasty is now the UK adult default - over 95 percent long-term success, day-1 discharge in most cases and superior dexterity for a fine anastomosis. Laparoscopic is equivalent in expert hands. Open is reserved for redo or very complex anatomy. Endopyelotomy is a smaller endoscopic option for short strictures with no crossing vessel.

  • How long does the JJ stent stay in?

    Four to six weeks in most units, occasionally longer for a complex reconstruction or if a leak occurred. Removal is a 15-minute day-case procedure under a short GA or with topical anaesthetic in the flexible cystoscope suite. Stent symptoms (frequency, mild flank pain) settle within days of removal.

  • How successful is it?

    Primary robotic and laparoscopic pyeloplasty give over 95 percent long-term success - measured as improved drainage on MAG3, resolved pain and preserved or improved kidney function. Redo pyeloplasty and cases with very poor pre-op function are more challenging, with success closer to 80 to 90 percent.

  • How much does private pyeloplasty cost in the UK?

    Roughly £13,000 to £19,000 for robotic, £11,000 to £16,000 for laparoscopic, £12,000 to £17,000 for open and £5,500 to £8,500 for endopyelotomy. Stent removal adds around £450 to £850.

  • How long is recovery?

    Robotic and laparoscopic: back to office work in 2 to 3 weeks, driving at 2 weeks, full activity by 6 weeks. Open: 4 to 6 weeks off work and 6 to 8 weeks to full activity. Stent symptoms until removal at 4 to 6 weeks. MAG3 renogram at 3 months confirms the reconstruction has held.
