Is Cryotherapy a Genuine Rival to Robotic Assisted Partial Nephrectomy in the Management of Suspected Renal Malignancy? a Systematic Review and Meta-Analysis

We systematically reviewed world literature and compare oncological outcomes, morbidity, renal function and peri-operative outcome between cryotherapy (CA) and robotic assisted partial nephrectomy (RAPN) for suspected renal malignancy. There was a statistically significant difference for "recurrence rates" between the 2 techniques, favouring the RAPN cohort. There was no statistically significant difference in overall and ≥Clavien 3a complication rates between the 2 techniques. The quality of evidence for recurrence rates, overall complication and ≥Clavien 3a were 'moderate', 'low' and 'very low' respectively on GRADE approach. If a nephron sparing approach is indicated, RAPN should be the approach of choice.
