RESUMEN
A man in his early 20s, originally from north-central Africa, presented with a high incidental serum creatinine level. A non-contrast CT scan was taken which was suggestive of urinary schistosomiasis. The diagnosis was confirmed on obtaining biopsies from the bladder. Due to bilateral hydronephrosis, an attempt at bilateral renal decompression was made. This failed to improve renal function. He eventually underwent a right nephrectomy. He is in end-stage renal failure, undergoing long-term dialysis, and has been placed on the waiting list for renal transplant.

Use of robot-assisted surgery is increasing since its advent in the 1990s. Robotic surgical training is the subject of much interest. Robotic technology would seem to facilitate training allowing more rapid attainment of competence. The safety and success of a particular surgical team depends on adequacy of training of its members. A learning curve is a way of describing the changes observed in surgical outcomes with increasing experience of the surgeon and can be used to plan training programs. The majority of published papers regarding learning curves are retrospective with small numbers of surgeons with different levels of experience comparing a variety of different outcomes. In this review, we describe the published literature on learning curves in robotic urological surgery, with the aim of offering a guide to both experienced and naïve surgeons who plan to learn new robotic procedure.

OBJECTIVES: To assess the prevalence of preoperative anemia and the impact of preoperative anemia and blood transfusion requirement on 30- and 90-day complications in a cohort of patients undergoing robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC). PATIENTS AND METHODS: IRARC was performed on 166 patients between June 2011 and March 2016. Prospective data were collected for patient demographics, clinical and pathologic characteristics, perioperative variables, transfusion requirements, and hospital length of stay. Thirty- and 90-day complications were classified according to the modified Memorial Sloan Kettering Cancer Center Clavien-Dindo system. RESULTS: Preoperative anemia was common (43.4%) and greatest in patients receiving neoadjuvant chemotherapy (48.6%) (p < 0.001). Patients with preoperative anemia were significantly more likely to have an Ileal conduit (p = 0.033), higher cystectomy stage (≥pT3) (p = 0.028), and a lower lymph node yield (p = 0.031). Preoperative anemia was not associated with increased perioperative morbidity but was associated with the requirement for blood transfusion (p = 0.001). Blood transfusion required in 20.4% of patients with intraoperative and postoperative blood transfusion rate was 10.2% and 13.9%, respectively. The 30-day all complication rate and 30-day major complication rate were 55.4% and 15.7%, respectively, while 90-day all complication rate and 90-day major complication rate were 65.7% and 19.3%, respectively. Intraoperative blood transfusion was not associated with increased complications, but postoperative blood transfusion requirement was independently associated with perioperative morbidity: all 30-day complications (p = 0.003), all 90-day complications (p = 0.009), and 90-day major complications (p = 0.004). CONCLUSION: The presence of preoperative anemia in patients undergoing iRARC is not associated with increased surgical risk, although preoperative anemic patients were significantly more likely to require blood transfusion. Blood transfusion requirement and specifically postoperative blood transfusion are independently associated with perioperative morbidity and are an important factor for the optimization of postoperative outcomes.
