Practice Trends in the Surgical Management of Renal Tumors in an Academic Medical Center in the Past Decade

Abstract

Objectives. To evaluate the trends of surgical treatment of the renal tumor in an academic medical center. Methods. Between 2001 and 2010, 505 were treated surgically at the Federal University of Sao Paulo for renal tumors. The following variables were observed and analyzed according to their evolution through time: frequency and types of surgeries performed, operative time, hospital stay, and warm ischemia time for partial nephrectomy.Results. An increase in the frequency of laparoscopic radical nephrectomies, open partial nephrectomies, and laparoscopic partial nephrectomies was observed when comparing the periods from 2001 to 2005 (4.3%, 2.6%, and 12.6%, resp.) and from 2006 to 2010 (13.2%, 18.6%, and 20.2%, resp.; < 0.001). The average of operative time, hospital stay, and tumor size diminished (from 211.7 to 177.17 minutes, from 5.52 to 4.22 days, and from 6.72 to 5.29 cm, resp.) when compared to the periods from 2001 to 2005 and from 2006 to 2010 ( < 0.001, = 0.016, < 0.001, resp.). Conclusion. As time goes by, there has been a significant reduction in the hospital stay time, surgery time, and size of renal tumor in patients treated surgically. The frequencies of minimally invasive and nephron-sparing surgeries have increased over the last years.

Surgical Management of Renal Cell Carcinoma

“…Matheus et al in a case series of 505 patients also reported similar findings. 17 The surgical complications were graded according to the Clavien-dindo system. Three patients in the laparoscopic group developed complications whereas 5 patients developed complications in the open approach, however, this is not statistically significant (P-value = 0.230).…”

Trends in the surgical management of renal cell carcinoma in a contemporary tertiary care setting

“…A study of 505 patients from brazil reported that the average age, operative time, hospital stay, and renal tumor size were 56 years (17–84), 190.3 min (55–630), 4.7 days (1–60), and 5.9 cm (0.5–28), respectively. [ 38 ] Their results showed there was a significant decrease in operative time, length of hospital stay, and tumor size when comparing laparoscopy to open surgeries between the periods of 2001 to 2005 and 2006 to 2010. And these three variables in our data show a similar pattern of results.…”
