About diagnosis, treatment and recovery
What is ureteropelvic junction (UPJ) obstruction and why is surgery needed?
The UPJ is where the renal pelvis meets the ureter; a narrowing here obstructs urine flow and can cause hydronephrosis and loss of kidney function, so surgery is needed to restore free drainage.
Is hydronephrosis dangerous and what happens if it is left untreated?
Hydronephrosis is dilation of the kidney from urine buildup; left untreated it can gradually reduce kidney function, so relieving the obstruction is important.
What are the advantages of robotic pyeloplasty over open and laparoscopic surgery?
The robotic approach offers small incisions, less bleeding and rapid recovery; with three-dimensional vision and wristed instruments it gives more comfortable control, especially for fine suturing and knot-tying.
Which tests (scintigraphy, CT/MR urography) are done before surgery?
For diagnosis and planning, ultrasound, CT/MR urography and renal scintigraphy (diuretic renogram) are typically performed to assess the obstruction and kidney function.
Why is a DJ (double-J) stent placed and when is it removed?
A DJ stent is placed to protect urine drainage and support the suture line while the anastomosis heals; it is removed at the appropriate time with a simple procedure.
How long does the operation take and how long will I stay in hospital?
Times vary by case; thanks to the small incisions a short hospital stay is usually sufficient. Your personalized timeline is shared after assessment.
What is the recovery process and return-to-work time after robotic pyeloplasty?
Small incisions allow fast mobilization and an early return to daily life; your individual recovery and return-to-work time is determined by our team.
How is the success of the surgery evaluated and how is drainage followed up?
Success is evaluated by objectively monitoring drainage and kidney function with postoperative imaging and renal scintigraphy (diuretic renogram).
How does the surgery change if there is a crossing vessel?
If an aberrant crossing vessel compresses the junction, the anastomosis is brought in front of the vessel (transposition) to relieve the compression.
Is redo pyeloplasty possible for patients whose previous repair failed?
Yes; redo pyeloplasty, which requires millimetric dissection within scar tissue, is an advanced reconstructive repair where robotic precision is especially valuable.
How does the process work for international patients?
Our end-to-end international patient service covers visa, transfer, accommodation and medical interpreter support; the process is started remotely by sharing your file.
