Brief Summary:
Randomized open-label clinical trial to compare renal volumetry pre and post operative in patients undergoing two types of partial nephrectomy techniques for renal tumors robot-assisted vs videolaparoscopic
Detailed Description:
Renal tumors are an important public health issue representing approximately 42 of all newly diagnosed cancers around the world Renal tumors are more prevalent in adults over 45 years old and with higher frequency in men than women Many risks factor have already been identified including smoking increase in twice the renal cancer risk obesity hypertension and renal cancer familiar history
Surgery is one of the main treatment options for renal tumors and is considered the only curative treatment for localized ones The most common surgeries used to treat it are Partial Nephrectomy PN and Radical Nephrectomy RN PN in indicated for smaller tumors smaller than 4cm size once it has already demonstrated renal function preservation and decrease chronic kidney disease CDK risk and cardiovascular events Furthermore RN is indicated for bigger tumors or for those who are centrally located in the middle of the kidney
In the last years PN use have been increased and consequently RN use has been decreased
According to a recent published study PN use for T1a tumors increased from 202 in 2004 to 597 in 2015 Furthermore 5-year cancer survival rates between patients undergone PN or RN was similar with PN being more associated with lower general mortality rates However PN is technically more challenging and is associated with complications and local higher recurrence risks
Both are viable surgery options for renal tumors and the chosen technique of them should be considered according to surgeon expertise patients comorbidities and tumor characteristics
There are some PN ways including Open OPN Laparoscopic LPN and robot-assisted RAPN however the best technique is still unknown Some studies have been comparing this three and a recent 39-studies metanalysis evaluating 11310 patients reported RAPN is which presented lower general complications less warm ischemia period and higher kidney function preservation rates in comparison with LPN or OPN Other 29-studies metanalysis evaluating 5952 patients showed RAPN presented lower surgical and hospitalization periods compared to OPN and LPN However RANP is associated with higher costs and a longer learning curve than other NP techniques
Renal volumetry is an important measure for kidney function evaluation which aids on surgical approach choose for NP In the present there are some ways to evaluate pre and post operative kidney volumetry such as TC RMN and 3D ultrasonography 3DUS A systematic review and metanalysis of 26 studies analyzed 1918 patients and showed TC preoperative renal volumetry is the best way to predict postoperative kidney function and the need for a NP Renal volumetry by TC and RMN postoperative also were considered good trustful measures to evaluate volumetry and remained kidney functions after PN 3DUS appear to be a more economic and good measure to evaluate it with a good precision compared to what was found to TC and RMN
In general pre and postoperative renal volumetry are an important measure to guide surgeons on the best surgery approach in PN and right renal volumetry image evaluation should be considered according to costs available patients characteristics and surgeon experience Then this study aims to compare NP techniques VPN and RAPN using renal volumetry pre and postoperative
