German National Registry for NSS

Kidney Neoplasm

The G-NeSS Registry prospectively collects data on clinical and outcome variables from patients undergoing partial nephrectomy for renal masses. Analyses of data aims at identifying key factors determining the quality of surgical care in this patient population.

Today the majority of patients with renal tumors is diagnosed with localized disease amenable to nephron-sparing surgery (NSS). Partial nephrectomy (PN) constitutes the reference standard treatment for small renal masses according to international guidelines. Open PN ist still the predominant apporach in Germany, but the use of minimally-invasive surgery has continously increased over the last decades. Specifically, robotic surgery is on the rise and may facilitate the adoption of a minimally-invasive PN approach even in more complex renal tumours. Real world data on the outcomes of PN according to the surgical approach are limited. Data from cancer registries and health insurance databases usually lack important information an key patient und tumour characteristics, such as tumour complexity. The G-NESS registry database aims at prospectively collecting such clinical and outcome data from patients undergoing PN. Data collection includes perioperative variables on patient characteristics, tumour location and complexity, surgical approach, intra-/postoperative complications, and kidney function. Follow-up based on questionnaires is conducted after predefined intervals (i.e. 30 days, 12 months, 24 months, and 60 months) in order to receive information on long-term kidney function, comorbidities, and survival. The information received from the database can help to better define the optimal surgical care for patients with renal masses.
