Factors related to early castration resistance in metastatic prostate cancer. Results from the National Prostate Cancer Registry in Spain

Abstract Introduction The objective of the study was to determine the factors independently related with the development of castration resistance (CR) in prostate cancer (PC) in the medium term. Material and methods 155 patients diagnosed with metastatic PC with a follow-up of up to 39 months. Data taken from the National PC Registry. The evaluated variables were age, PSA, nadir PSA, Gleason, perineural invasion, TNM stages, and ADT type (intermittent / continuous). Results Mean follow-up 26,2 ± 13,4 months. 47.1% developed early CR, with mean time until onset of 12,2 ± 8,7 months. Univariate analysis: the mean PSA was correlated with CR (290 ± 905,1 ng/mL in non CR, 519,1 ± 1437,2 ng/mL in…

Holmium Laser Endoureterotomy With the Lovaco Technique for the Treatment of Ureterointestinal Stenosis: Step by step.

Abstract Objective To describe holmium laser endoureterotomy with the Lovaco technique for the treatment of ureterointestinal stenosis. This common problem after cystectomy represents a surgical challenge, with endourological techniques being useful in this context. We present a technique that has been described before, but which we consider useful and decisive. The key points and difficult aspects of the technique are shown, along with our experience with it. Methods We collected data on cases of ureterointestinal stenosis treated using holmium laser endoureterotomy with the Lovaco technique, in a prospective manner, between January 2017 and January 2018. Intraoperative data, postoperative…

Endoureterotomy with the Lovaco technique for treatment of ureterointestinal strictures: outcomes in an experienced center and factors associated with procedural success or failure.

INTRODUCTION The study aimed to present the outcomes of an endoureterotomy series using the Lovaco technique for the treatment of ureterointestinal strictures. Factors influencing the success or failure of this technique were also determined. MATERIALS AND METHODS Data were collected from all endoureterotomies for ureterointestinal strictures performed in a single-center between 2017 and 2020. Clinical variables and characteristics of the stricture were recorded in each case, and success was defined as the complete resolution of ureterohydronephrosis. Univariate analysis was used to correlate the variables recorded with procedural success or failure. RESULTS A total of 25 patients were recr…

Comparison of three different antibiotic protocols in transurethral resection of bladder tumour and the possible infectious risk factors: A non-randomized, prospective study

Introduction: We sought to investigate three different antibiotic protocols in transurethral resection of a bladder tumour (TURBT), and the possible infectious risk factors of this surgery.Methods: We conducted a non-randomized, prospective study, gathering cases of patients in whom TURBT had been performed. The sample was divided into three groups based on those who received antibiotics as: a single preoperative dose (Group A); a preoperative dose, plus a long protocol during the hospitalization (Group B); a preoperative dose, plus a long protocol during the hospitalization, plus five days at home (Group C). Intra- and postoperative data that could be relevant to infections was gathered.Re…
