“In terms of cancer epidemiology, the Czech Republic is one of the most severely affected countries not only in Europe, but in the world. Twenty-seven thousand people die of cancer here every year. Prostate cancer is the most common form of cancer among men in the Czech Republic,” says Tomáš Chmelenský, head of the Urology Department at Canadian Medical.

MUDr. Tomáš Chmelenský, Chief Urologist

YMCA Clinic

After graduating from the 1st Faculty of Medicine of Charles University in Prague in 2004, MUDr. Chmelenský travelled to the United States and Germany, where he completed internships focused on the surgical treatment of urethral strictures, particularly urethroplasty with a buccal graft and perineal prostatectomy. Between 2006 and 2016, he worked professionally at the Central Military Hospital in Prague and at the Regional Hospital in Příbram.

MUDr. Chmelenský has been a member of the Canadian Medical team since 2016. His areas of specialisation include cancer, urinary tract diseases, voiding disorders, phimosis, diseases of the male reproductive organs, haematuria, urinary tract infections, kidney stones, urinary incontinence, andropause and, of no less importance, erectile dysfunction.

MUDr. Mokriš graduated with a degree in general medicine from the Faculty of Medicine of Charles University in Plzeň and gained experience at the Department of Urology at Thomayer University Hospital in Prague, where he has been working since 2012. He has also been focusing on his Ph.D. studies in the field of functional urology at the 3rd Faculty of Medicine of Charles University in Prague since 2015. In addition to his medical practice, he has several professional publications to his name. Among other things at Canadian Medical, he performs minimally invasive and non-invasive surgical procedures.


MUDr. Jan Kříž

AFI Clinic

Upon successfully completing his studies in the field of general medicine at the 1st Faculty of Medicine of Charles University in 1979, MUDr. Kříž began working at the Urology Clinic of the General University Hospital in Prague. In 2001, he transferred to the Paediatric Surgical Clinic at Motol University Hospital, where he still serves as the chief paediatric urologist. At the same time, he is an assistant professor at the Urology Clinic of Motol University Hospital. He focuses especially on the treatment of children with congenital and acquired disorders of the urinary tract and genital diseases in boys. In addition to his professional practice, he also focuses on publishing and lecturing.


New instruments and procedures at the AFI Outpatient Urology Department

At Canadian Medical, we strive to offer our patients the best care available using state-of-the-art methods and instruments. The AFI Outpatient Urology Department has several new things that will further improve the quality of the offered services.

Samsung V7 ultrasound

Ultrasound is a practically indispensable tool in the field of urology. It is most commonly used for detailed examination of the kidneys and bladder, though it can also be used to examine the prostate and structures in the scrotum, particularly the testicles. It serves for the detection of urinary-tract pathologies such as kidney, bladder, prostate and testicular cancer. Ultrasound is also useful for diagnosing urinary concrements (stones) and ruling out urinary outflow disorders, as well as for measuring the residue in the bladder after urination and the size of the prostate with respect to micturition disorders. The new Samsung V7 high-end digital colour ultrasound machine will help to improve the accuracy of all such examinations.

Prostate biopsy under visual control using the Samsung V7 ultrasound machine

The AFI clinic now performs prostate biopsies under visual control using a Samsung V7 ultrasound machine. This procedure is usually performed on men in whose case prostate cancer is suspected. The main indications for a prostate biopsy include a persistently elevated PSA (prostate specific antigen) or PHI (prostate health index) value in blood samples, a suspicious lesion shown in an MRI scan of the prostate, or a pathology suspected in a physical examination of the prostate via the rectum.

Minimally invasive no-scalpel vasectomy

This procedure involves surgical severance of both sperm ducts in the scrotum under local anaesthesia, which is the most reliable method of male contraception. The surgical procedure is minimally invasive thanks to the use of special surgical instruments, which reduces the risk of surgical and post-operative complications. The post-operative healing time is also reduced to a minimum. The procedure is performed in an outpatient operating room.

Uro biofeedback

A new feature in the outpatient urology department at the YMCA clinic is the Biofeedback treatment method, i.e. an exercise using feedback mediated by a visual or acoustic correlate of pelvic-floor activity, where the exerted pressure is depicted on a monitor by means of a curve. The purpose of the treatment is for the patient to learn to relax the pelvic floor and engage the relevant muscles. This exercise is appropriate for people who have problems with incontinence, people with post-operative problems, women after childbirth and menopausal women.

Other methods offered at Canadian Medical

In addition to the new methods and instruments mentioned above, Canadian Medical offers a broad range of examinations and procedures performed by top specialists. Canadian Medical has three outpatient urology departments with a broad range of modern diagnostic and therapeutic equipment and instruments that provide comprehensive urological care, from basic physical examination methodologies to complete instrument-based and functional examinations. At the same time, we possess high-quality sonographic equipment, which enables the performance of non-invasive examinations of the urinary tract. These devices are also used for prostate biopsies and functional examination of the urinary tract.

We also offer the possibility of uroflowmetry, which is used to assess functional disorders of the lower urinary tract. The outpatient urology departments have modern types of flexible cystoscopes with which it is possible to gently diagnose diseases of the urethra and bladder in great detail. We cooperate with the department of radiodiagnostics (CT, MR, X-ray) in determining diagnoses. In cooperation with the laboratory, we are able to collect a full range of laboratory values, including the latest cancer markers, in our outpatient urology departments.

The most common procedures that we perform in our outpatient urology departments include prostate biopsies, uroflowmetry, vasectomies and ultrasound examinations of the urinary tract and reproductive organs. Flexible cystoscopy, i.e. endoscopic examination of the urethra and bladder, and frenuloplasty, in which the shortened frenulum of the penis is elongated, are also very commonly performed procedures.
