Urology Practice in Kelina Hospital has been responsible for most of our milestones. For example:
The first Percutaneous Nephrolithotmy (PCNL) in Nigeria was done in Kelina Hospital.
Dr Undie was the first Nigerian Urologist to do PCNL on his own, using ultrasonic, laser and pneumatic lithotripsy.
The first Minipercutaneous Nephrolithotomy (Miniperc) in Nigeria was done in Kelina Hospital by Dr Undie.
Kelina Hospital was one hospital in Nigeria that started doing Bipolar TURP for prostate from the very beginning, rather than monopolar which everybody else was doing at that time.
The first laparoscopic radical prostatectomy for prostate cancer in Nigeria was done in Kelina Hospital.
The first laparoscopic pyeloplasty for Pelvi-ureteric Junction Obstruction or PUJ obstruction in Nigeria was done by Dr Undie.
Kelina Hospital is the first hospital in West Africa to acquire the Swiss Lithoclast Master for PCNL.
About half our Urology patients go home same day after surgery. More than 90% of our urological surgeries are done through Minimal Access Surgery (endoscopic or laparoscopic). Urology is the busiest department in Kelina Hospital.
