  • Treatment of upper urinary tract urothelial carcinoma (UTUC)/transitional cell carcinoma (TCC) with minimally invasive endoscopic treatment using flexible ureteropyeloscopy and resection/ablation of the superficial lesions as well as radical nephroureterectomy with laparoscopic or open access surgery.
  • Treatment of renal cancer by applying both laparoscopic or open partial nephrectomy, and laparoscopic or open radical nephrectomy.
  • Treatment of prostate cancer using open and laparoscopic techniques, while at the same time, maintaining urinary continence and erectile function.

  • Treatment of penile cancer with either partial or total penectomy.
  • Treatment of testicular cancer.


Reconstructive urology

  • Treatment of the ureteropelvic junction syndrome using minimally invasive techniques such as, ureteroscopic and percutaneous Laser endopyelotomy, as well as laparoscopic pyeloplasty.
  • Ureteral stricture with endoscopic treatment (stricture dilation, laser transureteral resection, intraluminal Memokath stent placement)
  • Treatment of urethral strictures with endoscopic treatment and urethroplasty using grafts, as well as treatment of urethral meatal stenosis with the application of meatotomy.


Endourology and lithiasis

  • Extracorporeal lithotripsy for all calculi (stones) (kidney, ureter, bladder)
  • Endourological treatment of ureteral calculi, applying both rigid and flexible ureteroscopes and using Holmium laser for stone ablation.

Moreover, the department uses combined treatment with percutaneous access as well as flexible ureteropyeloscopy (ECIRS).
