About

Kristina Wittig is a leading urologic oncologist whose research focuses on advancing surgical outcomes for patients with bladder and prostate cancers, particularly through the refinement of robot-assisted radical cystectomy (RARC). Her landmark 2014 study, cited 36 times, provided critical intermediate-term oncologic outcomes for RARC in urothelial carcinoma, establishing benchmarks for cancer control in minimally invasive surgery. Wittig’s work on hospital readmission and cost burden, with 24 citations, revealed the economic and clinical challenges of post-surgical care, offering actionable insights to reduce healthcare costs and improve patient recovery. She also pioneered nerve-sparing techniques in RARC, demonstrating in an 18-citation study that bilateral cavernosal nerve preservation can preserve erectile function in preoperatively potent patients—a significant quality-of-life advancement. More recently, Wittig has explored predictive modeling, using two-stage classifiers to integrate PCA3 and PSA proteolytic activity for forecasting prostate cancer recurrence, a novel approach that could personalize follow-up care. Her contributions have shaped modern urologic surgery, blending technical innovation with patient-centered outcomes, and her work continues to influence clinical guidelines and surgical practice.
