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

Introduction: Ureteral stent placement during laparoscopic pyeloplasty is a common procedure in pediatric patients. Although an apparently safe maneuver, ascending placement of the stent can lead to complex removal or repositioning reinterventions.

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.

Material And Methods: A 63-year-old man underwent BCG treatment for a bladder tumor with pathological diagnosis of T1G3 urothelial carcinoma.

Early Ultrasound after Endoscopic Puncture of Ureterocele: Signs that Show Surgical Treatment Success.

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.

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.

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.

[Pediatric ureteral ectopia: Solutions for several issues.].

Objective: The treatment of the ectopic ureter in the pediatric patient must be individualized in each caseMETHOD: Description of clinical cases, therapeutic management and evolution of patients.

Results: We present four pediatric patients with ectopic ureters who underwent surgery. We describe a case of laparoscopic nephroureterectomy, one of laparoscopic uretero-ureterostomy, one of bilateral ureteral reimplantation and another of unilateral reimplantation.

[Penile Cancer: A case for non-lymph node disease following a negative sentinel node exploration.].

Objective: To describe the case of a patient with subcutaneous inguinal recurrence of penile cancer without lymph node involvement.

Methods: Description of a clinical case and review of the literature on the subject.

Results: We present the case of a 72-year-old man with penile cancer and extranodal inguinal extension that affected subcutaneous cell tissue, with a history of negative sentinel lymph node and subsequently without invasion of the regional lymph nodes in lymphadenectomy after chemotherapy.

Endoscopic Treatment of Complete Ureterointestinal Stenosis Without Antegrade Ureteroscopy.

Ureterointestinal stenosis is a frequent complication after radical cystectomy, occurring in up to 10%-12% of cases. Endoscopic treatment of complete stenosis has been described through double access, with antegrade flexible ureteroscopy and simultaneous retrograde endoscopy through the intestinal diversion. We present a case of endoscopic treatment without use of antegrade ureteroscopy.

Dislodgement in Long-Term Patients with Nephrostomy Tube: Risk Factors and Comparative Analysis Between Two Catheter Designs.

To determine possible risk factors for accidental nephrostomy tube dislodgement and compare two different tube types in this context in patients with chronic catheters. We conducted a retrospective study of long-term patients with nephrostomy tube. We performed a comparative analysis, studying the possible variables that were related to catheter dislodgement.

Ureteral realignment with combined access as a treatment of complete ureteral transection.

Ureteral realignment using a ureteral stent can be an alternative treatment in cases of complete ureteral transection and may avoid the need for reconstructive surgery. The combined access can help the passage of the guidewire through the injured area and the threading of the urinary system of the patient. We present a case of a 38-year-old man with multiples abdominal surgeries, who underwent a complete ureteral section treated with ureteral realignment with combined access.
