Prof. Wang Zhongyang has been engaged in urology for nearly forty years, specializing in minimally invasive treatment of urological stones. He has presided over a variety of stone-related surgeries and achieved good results, and has a wealth of experience. After seeing Dmitri, Prof. Wang patiently listened to his discomfort and arranged for a urological ultrasound firstly, which initially revealed multiple stones in both kidneys, stones in the bladder, and prostate hyperplasia and calcification.

In order to define the size, location and nature of the stones more precisely, Prof. Wang arranged for Dmitri to undergo a urological CT scanning + dual energy imaging examination, which indeed revealed the key problem - not only were there stones in both kidneys, but also in both kidneys, and in both kidneys, there were stones in both kidneys.A large stone measuring about 13.2 mm x 10.6 mm was also hidden in the bladder adjacent to the left ureter.

What's even more unusual is that this stone isn't just any bladder stone.It “hid” in the lower ureter and was partially embedded in the bladder wall, like a “bullet” stuck in the wall.A CT dual energy scan showed a mixed composition stone (part urate, part non-urate).

This stone is stuck in the ureter and the bladder connected to the “throat”, not only caused the obstruction of urine flow, but also because of the location of the special, ordinary examination is easy to miss the diagnosis.

First of all, the lower part of the ureter is the “last gate” for urine to flow from the kidneys to the bladder, and this part of the tube is naturally very narrow, with a diameter of only 2-3 millimeters.A 13mm x 10.6mm stone stuck here is like a ping pong ball blocking a straw - the urine simply can't get through.

What's more, this stone is not an ordinary blockage. It has partially “grown” into the bladder wall, like a stone embedded in the wall, from the inside of the bladder can not be reached, from the outside and can not enter, not a simple take can be resolved. If delayed and not dealt with, it may lead to severe hydronephrosis, recurrent urinary tract infections, and even slowly destroy kidney function.

Many people may not be aware that the ureter itself has three physiologic strictures, and the narrowest and most difficult to operate on is the one that enters the bladder (the inner section of the bladder wall). The anatomy here is very special, surrounded by a wealth of nerve and muscle tissue, and the slightest carelessness during surgery may injure the surrounding area. In addition, the location of the stone is too deep and too low, so there is very little room for the surgical instruments to move, and the difficulty of the operation rises sharply.

To make matters worse, Dmitri was 68 years old and had a combined prostate enlargement - the urethra itself was narrower and more curved. The three mountains of stones, age, and prostate problems pressed together to make this surgery far more difficult than a normal bladder stone.

After meticulous discussions, Prof. Zhongyang Wang's team finalized the most suitable treatment plan for him - theTransurethral cystoscopy with laser lithotripsy for bladder stonesThe most important advantage of this type of surgery is that it is minimally invasive. This is a minimally invasive procedure with the biggest advantage of being non-invasive on the surface of the body. It doesn't require any incisions in the abdomen or skin, but only requires the placement of a cystoscope through the body's natural urethra, which allows the stone to be precisely located, with little damage to the body, less bleeding and a quicker recovery, which makes it ideal for patients such as Dmitri, who have a higher requirement for post-operative recovery.

On the day of the surgery, the operation was carried out smoothly under the supervision of Prof. Wang Zhongyang.First, the bladder is entered under direct vision through a ureteroscope, and the middle lobe of the prostate, which has obvious hyperplasia, is clearly seen. Holmium laser fiber is then introduced, and the high energy of the holmium laser is used to accurately powder large stones hidden in the bladder wall, and then all of these powdered stones are suctioned out.

During the whole process, the operation was precise and delicate. After the operation, the bladder mucosa was examined with an electrosurgical microscope and found to be free from any obvious damage, so the operation was successfully completed and Dmitri returned to the ward without any problems. Dmitri recovered very quickly because the surgery was minimally invasive, and in a short time, he was free from urinary discomfort and was able to live and work normally.

Why Choose

 Kai Keung Memorial Hospital International Medical Department?

As an expatriate, Dmitri chose KKMH's International Medical Department for its international standards of care and service:

The department has introduced the international advanced technology of “prostate vapor ablation” and “prostate urethral dilatation” for the treatment of prostate hyperplasia. These two technologies are newly developed ultra-minimally invasive technologies for the treatment of prostate hyperplasia in recent years, and our hospital is one of the first hospitals in South China to introduce these two technologies and apply them in the clinic.
