Our approach
Urology care, mostly without large cuts
Urology covers the kidneys, ureters, bladder, prostate and male reproductive organs. Most stone, prostate and bladder operations are now done through the urine passage with a camera and laser, or by keyhole and robotic surgery, which means less pain and a faster return home.

Men’s health check
Prostate symptoms are common after 50
Most urinary symptoms in older men are due to a non-cancerous enlarged prostate, but they should be checked. Treatment can make a big difference to sleep and daily life.
When to get checked
Book a urology review if any of these apply:
- !Getting up 2 or more times at night to pass urine.
- !A weak or interrupted stream or straining to start.
- !Blood in the urine — even once, and even without pain.
- !A family history of prostate cancer — ask about PSA testing from age 45–50.
Urology care at Charak
- Consultations with our urologists.
- Prostate treatment — TURP and HoLEP.
- Kidney stone prevention with our dietitians.
Preventing kidney stones
Tap each one you do:
- I drink enough water to pass 2–2.5 litres of urine a day
- I drink more in summer and after exercise
- I keep salt low
- I limit red meat and very high-protein diets
- I do not cut out calcium-rich foods unless advised
- I limit cold drinks and packaged juices
- I had a follow-up scan after my last stone
Once you have had a stone, there is a chance of another. Prevention advice is based on your stone type and urine tests.

Recovery
After urology surgery
General guidance — always follow the specific instructions your urologist gives you.
With a DJ stent
A stent may cause mild discomfort, frequent urination or some blood in the urine. This is common.
The stent must be removed or changed on the date given — do not forget.
After prostate surgery
Drink plenty of fluids and avoid straining. Some blood in the urine is common for a few weeks.
Avoid heavy lifting, cycling and long drives for 4–6 weeks.
Living with a catheter
Keep the bag below the bladder and empty it regularly.
Clean around the catheter daily and drink plenty of fluids.
After keyhole or robotic surgery
Walk from the day after surgery and keep the wounds clean and dry.
Avoid heavy lifting for the time your surgeon advises.
Preventing stones coming back
Drink enough water to keep urine pale.

FAQs
Frequently asked questions
Will my kidney stone pass on its own?
Stones under about 5 mm often pass with fluids and medicines. Larger stones, or stones causing infection or blockage, usually need treatment.
Which is better — laser, PCNL or lithotripsy?
It depends on the size, position and hardness of the stone, and your kidney anatomy. Your urologist will recommend the option most likely to clear the stone safely.
How long does a DJ stent stay in?
Usually 2–6 weeks, depending on the procedure. It must be removed or changed on time to avoid problems.
Is prostate surgery safe for older men?
Most men, including older men, recover well after TURP or HoLEP. Your fitness for surgery is checked carefully beforehand.
Does a raised PSA mean cancer?
Not always. PSA can rise with an enlarged prostate or infection. Your urologist may repeat the test or advise an MRI or biopsy.
Is robotic surgery available for urology?
Yes. Robotic surgery on the da Vinci Xi system is used for selected kidney, bladder and prostate operations.
Can I donate a kidney to a family member?
Healthy adults can often donate after detailed tests. Donation must follow the transplant law and needs approval.
How do I book an appointment?
