Long surgical waiting list times are associated with an increased rate of negative ureteroscopies.

Introduction: Negative ureteroscopy (NURS) is "a ureteroscopy in which no stone is found during the procedure." We aimed to determine the association between the surgical waiting list time (WLT) and the NURS rate.

Methods: We retrospectively analyzed all patients scheduled for ureteroscopy in our center between January 2017 and July 2019.

Iterative renal transplantation: our experience on third transplants.

Purpose: To report our experience on third kidney transplantation, analyzing the complications and graft survival rates as compared to previous transplants.

Methods: Retrospective study of third renal transplants performed at our center. Outcomes were compared with a cohort of first and second transplants.

Analgesic refractory colic pain: Is prolonged conservative management appropriate?

Objectives: To propose a clear definition and management pathway of patients with analgesic refractory colic pain (ARCP).

Patients And Methods: Prospective cohort study from February 2018 to February 2019 including patients with ARCP defined as ongoing renal colic pain after one dose of IV NSAID, IV paracetamol, and a parenteral opioid, given sequentially in that order. Patients were observed in-hospital under full parenteral analgesic management for 8-12 h, whenever patients had minimal or absent pain after conservative management (CM) they were discharged, and followed-up with new imaging within four weeks.

[Training program on medical urology: Future perspectives.].

Urology is defined as the medical-surgical specialty that includes the study, diagnosis and treatment of medical conditions of the urinary system. It is well specified by the National Commission of Specialties that we must know the medical pathology that concerns us. However, on occasions, resident training focuses on the surgical field and oncological pathology, which, although one of the main pillars of the specialty, is usually to the detriment of training in medical and functional pathology.
