ABSTRACT Introduction: Dismembered open pyeloplasty described by Anderson and Hynes is the “gold standard” for the treatment of ureteropelvic junction obstruction. The aim of our study was to compare the results of open (OP) vs laparoscopic (LP) vs robotic (RALP) pyeloplasty. Material and Methods: A multicenter prospective review was conducted of pyeloplasty surgeries performed at five high-volume centers between 2014 and 2018. Demographic data, history of prenatal hydronephrosis, access type, MAG3 renogram and differential renal function, surgery time, length of hospital stay, and complication rate (Clavien-Dindo) were recorded. Access type was compared using the Kruskal-Wallis, Chi-square, or Fisher's exact tests. Results: A total of 322 patients were included: 62 OP, 86 LP, and 174 RALP. The mean age was 8.13 (r: 1-16) years, with a statistically significant lower age (mean 5 years) in OP (p < 0.001). There were no significant differences in the distribution of the side affected. Operative time was 110.5 min for OP, 140 min for LP, and 179 min for RALP (p < 0.0001). Hospital stay was significantly shorter in the RALP group than in the other groups (p < 0.0001). There were no differences in postoperative complications and reoperations between the three groups. Conclusions: Minimally invasive surgery for the management of UPJO in children is gaining more acceptance, even in patients younger than 1-year-old. Operative time continues to be significantly shorter in OP than in LP and RALP. Hospital stay was shorter in RALP compared to the other techniques. No differences were found in complication rates, type of complications, and reoperation rate.

ABSTRACT Medical and surgical priorities have changed dramatically at the time of this pandemic. Scientific societies around the World have provided rapid guidance, underpinned by the best knowledge available, on the adaptation of their guidelines recommendations to the current situation. There are very limited scientific evidence especially in our subspecialty of pediatric urology. We carry out a review of the little scientific evidence based mainly on the few publications available to date and on the recommendations of the main scientific societies regarding which patients should undergo surgery, when surgery should be performed and how patient visits should be organize.

Objectives: To perform a retrospective evaluation of surgical complications and morbidity in patients undergoing radical retropubic prostatectomy (RRP) as elective treatment for organ-con.ned prostate cancer in our center with previous transurethral resection of the prostate (TURP). Methods: Between 1980-2004 we performed 59 radical prostatectomies in patients with previous TURP. We analyze the morbidity and mortality of the RRP, its functional outcomes, and the accordance between clinical and pathological stage. Results: Mean time between TURP and RRP was 16 months. Mean patient age at the time of diagnosis was 63 years. Clinical stage: 16 T1a,18T1b,20T1c, 3T2a,2T2b. Average surgical time was 180 minutes. Intraoperative events: technical dif.culties in the dissection of the gland 57%, bladder neck preservation 27%, neuro vascular bundles preservation 3.39%, ureter ligation 1.69%, rectal laceration 1.69, urethrorrhagia 1.69%, urinary leak 5%, and blood transfusions 11.8%. Postoperative complications: urinary tract infection 10.17%, wound infection 10.17%, pelvic hematoma 5.08%, deep vein thrombosis 1.69%, and one sudden death of unknown cause one month after surgery . Pathologic report: 49pT2b, 8 pT3 and 2pT4. Late complications: erectile dysfunction 85.7%, vesicourethral anastomosis stenosis 10.3%, and complete urinary incontinence 3%. Conclusions: Radical retropubic prostatectomy in patients with previous TURP is technically more dif.cult and has comparable outcomes to RRP patients without previous TURP

Objetivo: Nuestro objetivo ha sido realizar una valoración retrospectiva en nuestro centro de las complicaciones quirúrgicas y de morbilidad en pacientes intervenidos de prostatectomía radical retropúbica como tratamiento electivo del cáncer de próstata órgano confinado, con antecedentes de resección transuretral de próstata (RTUp). Métodos: Entre 1980-2004 hemos realizado 59 prostatectomías radicales en pacientes con RTUp previa. Se analiza morbimortalidad de la PRR, resultados funcionales y concordancia entre estadiaje clínico y patológico. Resultados: El tiempo medio transcurrido entre la RTUp y la prostatectomía radical 16 meses. Edad media en el momento de diagnóstico de adenocarcinoma de próstata 63 años. Estadiaje clínico: 16T1a, 18T1b, 20T1c, 3 T2a, 2 T2b. La media de tiempo quirúrgico de la PRR 180 minutos. Incidencias intraoperatorias: Dificultades técnicas en la disección de la glándula 57%, preservación del cuello vesical 27%, preservación de bandeletas neurovasculares 3.39%, ligadura de uréter 1.69%, lesión rectal 1.69%, uretrorragia 1.69%, fístula urinaria 5% y el 11.8% requirió transfusión. Como complicaciones postoperatorias: ITU 10.17%, infección de la herida 10.17%, hematoma pélvico 5.08%, TVP 1.69% y un paciente falleció súbitamente al mes de la cirugía por causa no filiada. Estadío patológico: 49pT2b, 8pT3 y 2pT4. Como complicaciones tardías: Disfunción eréctil 85.7%, estenosis de la anastomosis 10.3% e incontinencia urinaria total 3%. Conclusión: La PRR en pacientes con RTUp previa es técnicamente más dificultosa con resultados comparables con los pacientes sin cirugía prostática previa
