Less radical tumor surgery can offer better long-term kidney function
Date:2/7/2011

Patients with kidney tumours larger than four centimetres are much more likely to enjoy good long-term renal function if they undergo nephron-sparing surgery rather than radical nephrectomy, according to a study in the February issue of the urology journal BJUI.

Researchers from the Department of Urology at Johannes Gutenberg University in Mainz, Germany, studied 166 patients for up 19 years, with a median follow up of five-and-a-half years. The participants were split into two groups - 81 "younger" patients up to 55 and 85 "older" patients aged 65 and over.

They found that, regardless of age, the patients who underwent radical nephrectomy (RN) were twice as likely to develop new onsets of chronic kidney disease than those who underwent nephron-sparing surgery (NSS).

"In RN the surgeon removes the whole kidney and the tissue around it, while in NSS the surgeon removes the cancer and part of the kidney surrounding it so that the patient still has some working kidney left after the operation" explains lead researcher Dr Frederik C Roos.

"Overall survival and complication rates were similar between the two groups, but long-term kidney function, which is very important to overall health and quality of life, was much better in the patients who had received NSS.

"Kidney tumours are more common in people in their 60s and 70s and increasing life expectancy means that more elderly patients will seek treatment for this condition.

"Our results show that 76% of older patients enjoyed good long-term kidney health with NSS as did 85% of younger patients.

"This is important as loss of kidney function is also associated with other health issues, including higher incidence of cardiovascular disease and cardiac deaths and reduced function in other organs."

Key findings included:

  • The incidence of chronic kidney disease in younger patients (aged 23 to 55) was 31% after RN an
