Novel kidney segmentation system to describe tumour location for nephron-sparing surgery

Abstract

Kidney segmentation (KS) system is an objective and reproducible radiologic method of universally reporting tumour location according to 12 renal segments. By adding descriptive information on tumour characteristics in candidates for nephron-sparing surgery, this novel KS system could serve as an adjunct to current nephrometry systems.

Robotic Unclamped “Minimal-margin” Partial Nephrectomy: Ongoing Refinement of the Anatomic Zero-ischemia Concept

“…Consequently, unclamped minimal-margin PN is optimally indicated for tumors located in the medial half of the kidney, including hilar, polar, and other medial locations. These correspond to the recently described anatomic kidney segments numbered 2, 4, 6, 8, 10, and 12 [16]. Future work is required to preoperatively identify the presence of a pseudocapsule and other tumor characteristics to personalize unclamped PN technique for tumor and patient features.…”

Editorial Comment to Robot‐assisted laparoscopic partial nephrectomy versus laparoscopic partial nephrectomy: A propensity score‐matched comparative analysis of surgical outcomes and preserved renal parenchymal volume

“…2 In this setting, preoperative imaging with a standardized method to report tumor location and nephrometry scores is crucial for choosing the most appropriate technique. 3 In the current study, Tachibana et al showed the superiority of robotassisted PN in terms of surgical outcomes, including renal function and the preserved renal parenchymal volume. 4 Nevertheless, surgical outcomes and volume loss are only part of all the aspects involved in renal function outcomes.…”

“…These goals can be reached by using tumor enucleation or minimal margin PN techniques and minimally ischemic or off‐clamp PN whenever feasible . In this setting, preoperative imaging with a standardized method to report tumor location and nephrometry scores is crucial for choosing the most appropriate technique . In the current study, Tachibana et al .…”

Volumetric assessment of unaffected parenchyma and Wilms’ tumours: analysis of response to chemotherapy and surgery using a semi‐automated segmentation algorithm in children with renal neoplasms

“…The present study represents an early evaluation of this technology for paediatric patients with WT, which to our knowledge, has not been previously reported. Earlier studies have described manual segmentation techniques, developed for radiologists to accurately describe tumour location and provide tissue volume assessments . However, we effectively trained a program to recognize WT features from CT scan images and differentiate it from adjacent structures and surrounding parenchyma, with minimal supervision from clinical staff.…”
