General Adult Urology

Whilst Dr Louie-Johnsun’s main interest is minimally invasive laparoscopic urological cancer surgery, he also treats most general adult urological conditions. This includes noncancerous prostatic obstruction (“BPH”) to urinary flow in men which can be treated with standard “re-bore” procedure called Transurethral Resection of the Prostate (TURP) or newer techniques with laser vaporesection of the prostate. He also utilises laser treatment for ureteric and kidney stones as well as surgical treatment and cystoscopic surveillance of bladder cancer. He also performs vasectomies.(See below)


Vasectomy is a safe and effective means of permanent contraception / sterilisation for a male by dividing and removing a portion of the tubes (vas deferens) that transport the sperm from the testes to the rest of the ejaculate fluid.

Although vasectomies can be performed under local or general anaesthesia, Dr Louie-Johnsun’s preference is to perform all his vasectomies under general anaesthesia in a hospital setting.


To be suitable for vasectomy you must:

  • Understand you will no longer be able to father children (ie completed your family)
  • Understand the operation is PERMANENT (although there are operations that attempt to reverse it)
  • Both you and your partner have discussed and agree on this form of contraception
  • Be aware of alternatives (female tubal ligation, the pill, IUCD, condoms)
  • Accept the risks of the operation which will be discussed with you but include pain, bruising, swelling, infection, post vasectomy pain syndrome, and failure


  • Resume work and normal activities (including protected sex) after 2 weeks
  • You must practice safe sex with another form of contraception until you are given clearance
  • Clearance is obtained with a semen analysis after 3 months and at least 20 ejaculations
    • 1/5 cases will require further testing as not all sperm has been cleared from the tubes (vas deferens)
  • You must have clearance by Dr Louie-Johnsun or his team with the semen analysis result before commencing unprotected intercourse
