Effect of time since vasectomy on live birth rate of TESE‒ICSI egg donation cycles and male-related prognostic factors.

Background: Vasectomy is a widely used method of contraception. However, some men may have the desire to become biological fathers again after a period.

Prospective comparison of two methods for correct ureteral stent placement in pediatric laparoscopic pyeloplasty.

Comparison between open and minimally invasive pyeloplasty in infants: A systematic review and meta-analysis.

Introduction: Ureteropelvic junction obstruction (UPJO) is the most common cause of congenital hydronephrosis. Techniques such as laparoscopic pyeloplasty (LP) have gained in popularity over recent years. Although some retrospective studies have compared minimally invasive reconstructive techniques with open surgery for treatment of UPJO in infants, results remain controversial due to the small sample size in most of these studies.

Introduction: We show the ability of early ultrasound after surgery to show the success of endoscopic puncture of the ureterocele.

Method: Description of the clinical cases, therapeutic management and description of the ultrasound findings.

Results: We present two infants aged 1 and 4 months who underwent endoscopic puncture of ectopic ureteroceles during a period of 3 months at our institution.

Use of Circular RNAs in Diagnosis, Prognosis and Therapeutics of Renal Cell Carcinoma.

Renal cell carcinoma is the most common type of kidney cancer, representing 90% of kidney cancer diagnoses, and the deadliest urological cancer. While the incidence and mortality rates by renal cell carcinoma are higher in men compared to women, in both sexes the clinical characteristics are the same, and usually unspecific, thereby hindering and delaying the diagnostic process and increasing the metastatic potential. Regarding treatment, surgical resection remains the main therapeutic strategy.

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.

Retrograde endoureterotomy as a treatment option for impacted calculus in the ureterointestinal junction.

Introduction: In patients with a history of radical cystectomy and with intestinal diversion, urolithiasis in the upper urinary tract is a frequent event.

Material And Methods: We describe for the first time a case of retrograde endoureterotomy used to treat a calculus proximal to the ureterointestinal junction.

Results: This technique is of interest when antegrade access is not possible.

TESE-ICSI outcomes per couple in vasectomized males are negatively affected by time since the intervention, but not other comorbidities.

Research Question: Does time since vasectomy (as obstructive interval) and the presence of different male comorbidities adversely affect the likelihood of achieving a newborn for vasectomized males undergoing testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI)?

Design: This retrospective study included 364 couples with vasectomized males undergoing TESE-ICSI cycles with autologous oocytes at IVI Valencia. The main outcome was live birth rate (LBR). Subjects were divided according to the male risk factor evaluated into quartiles (obstructive interval, body mass index [BMI]) or groups (hypertension, diabetes mellitus, dyslipidaemia).

Endoscopic treatment of intraluminal ureteral suture with holmium laser.

Although reconstructive surgery is the most accepted treatment for ureteral injury, there are reports of cases where endourologic treatment led to correct resolution of the problem. We present the case of a female patient aged 72-year-old who was previously underwent sacralcolpopexy because of anterior vaginal compartment prolapse. The patient underwent surgery to remove the mesh, due to the pain she had had since it was placed.
