When to see a urologist.
Urological symptoms can range from minor discomfort to serious conditions. Seeing a specialist in time often makes treatment much simpler.
- Painful urination
Pain or discomfort while urinating can be a sign of a urinary tract infection, stones or an enlarged prostate. - Frequent urination
Needing to urinate more often than usual, or feeling the urge even when your bladder is not full, can be a sign of infection, an overactive bladder or an enlarged prostate. - Blood in the urine (haematuria)
Blood in the urine can point to an infection, kidney stones or a tumour of the urinary tract. - Incontinence
Involuntary loss of urine can be caused by weak bladder muscles or an obstruction in the urinary tract. - Erectile dysfunction
Difficulty achieving or maintaining an erection can be a sign of an underlying urological condition, such as prostate problems or nerve damage. - Testicular pain
Often the result of inflammation, testicular torsion or a tumour. - Swelling or a lump on the testicle
A painless change may be a hydrocele or varicocele, but any new lump should be clarified promptly with an ultrasound. - Phimosis
Difficulty or inability to retract the foreskin over the glans of the penis.

Book a consultation →Urology — patients' most common questions.
Do I need a referral for a urology appointment in Zadar?
No. Appointments at Poliklinika Kranjčec are private, without a referral from a family doctor. You can book directly by phone or via the contact form.
How do I prepare for a urinary tract ultrasound?
For an ultrasound of the bladder and prostate it is best to arrive with a full bladder — drink 0.5–1 L of water about an hour before the examination and do not urinate immediately beforehand. No special preparation is needed for a kidney ultrasound.
When is a testicular ultrasound needed?
A testicular ultrasound is recommended for pain, swelling, a palpable lump, after an injury, or when a varicocele or hydrocele is suspected. The examination is quick and painless, and you receive the results immediately.
What is a cystoscopy and is it uncomfortable?
A cystoscopy is an endoscopic examination of the bladder using a thin instrument passed through the urethra. It is performed under local anaesthesia (gel), so discomfort is minimal and the examination itself takes just a few minutes.
From what age should men have their prostate (PSA) checked?
Regular prostate and PSA checks are recommended for men from the age of 50, or from 45 if there is a family history of prostate cancer. If you have urinary symptoms, an examination is advisable regardless of age.
Do I get my results immediately after the examination?
Yes. Most diagnostic procedures — the examination and ultrasound — are done in a single visit, and you receive the results and recommendations the same day.
Do you also treat women?
Yes. Urology covers the urinary system of both men and women — we treat urinary tract infections, incontinence, kidney stones and other conditions in all patients.
