Surgical outcome predictor analysis following hand-assisted or pure laparoscopic transperitoneal nephroureterectomy using the Taiwan upper urinary tract urothelial carcinoma database.

Purpose: Taiwan has a high incidence of upper tract urothelial carcinoma (UTUC). This study aimed to compare the surgical outcomes following transperitoneal hand-assisted laparoscopic nephroureterectomy (TP-HALNU) and transperitoneal pure laparoscopic nephroureterectomy (TP-LNU) from the Taiwan nationwide UTUC collaboration database using different parameters, including surgical volumes.

Materials And Methods: The nationwide UTUC collaboration database includes 14 hospitals in Taiwan from the Taiwan Cancer Registry.

A retroperitoneal cavernous hemangioma arising from the gonadal vein: A case report.

Rationale: Cavernous hemangioma (CH) is not commonly found within the abdomen or the retroperitoneum. We report the first case of CH originating from the gonadal vein.

Diagnosis: A retroperitoneal tumor was found incidentally in a 57-year-old female patient.

External validation of the Simplified PADUA REnal (SPARE) nephrometry system in predicting surgical outcomes after partial nephrectomy.

Background: Pentafecta is a major goal in the era of partial nephrectomy (PN). Simplified PADUA REnal (SPARE) nephrometry system was developed to evaluate the complexity of tumor. However, the predictive ability in pentafecta of SPARE system is yet to be determined.

Internal hernia from the interureteric space after robot-assisted radical cystectomy and urinary diversion: Two case reports.

Rationale: Radical cystectomy and urinary diversion remains the definite management for muscle invasive bladder urothelial cancer. Internal herniation caused by ureteral adhesion is an extremely rare complication after the procedure. To the best of our knowledge, this is the first case report of small bowel obstruction and internal herniation occurring between bilateral ureters and urinary diversion after robot-assisted radical cystectomy (RARC).

Outcomes of stage II-IV upper-tract urothelial carcinoma and adjuvant chemotherapy for locally advanced cancer.

The present retrospective study aimed to examine the outcomes of stage II-IV upper-tract urothelial carcinoma (UTUC) and determine whether adjuvant chemotherapy is a beneficial treatment for patients with locally advanced UTUC (specifically, stage III-IV). The analysis included 126 patients with muscle-invasive UTUC who were treated between June 2003 and June 2012. All patients underwent laparoscopic or open nephroureterectomy and bladder cuff excision.

Prostate Health Index (PHI) improves prostate cancer detection at initial biopsy in Taiwanese men with PSA 4-10 ng/mL.

In this study, we aimed to validate the Prostate Health Index (PHI) for the detection of prostate cancer (PCa). We prospectively enrolled patients aged 50-75 years with a serum prostate specific antigen (PSA) level of 4-10 ng/mL undergoing transrectal biopsy of the prostate between April 2016 and May 2017. The primary outcome was the diagnostic performance of various PSA derivatives (total PSA, free PSA, %fPSA, p2PSA, %p2PSA, and PHI) to predict PCa.

An unresectable retroperitoneal malignant fibrous histiocytoma: A case report.

Malignant fibrous histiocytoma (MFH) is most commonly observed in the extremities and the trunk but rarely in retroperitoneum. The present case report documents a 64-year-old man who was admitted with an abdominal palpable mass for 6 months. After a thorough investigation, a tumor of the retroperitoneum was identified adhered to adjacent organs and vessels.

A Mathematical Method to Calculate Tumor Contact Surface Area: An Effective Parameter to Predict Renal Function after Partial Nephrectomy.

Purpose: We proposed a mathematical formula to calculate contact surface area between a tumor and renal parenchyma. We examined the applicability of using contact surface area to predict renal function after partial nephrectomy.

Materials And Methods: We performed this retrospective study in patients who underwent partial nephrectomy between January 2012 and December 2014.

Spontaneous ureteral rupture and review of the literature.

Introduction: Spontaneous ureteral rupture is defined as non-traumatic urinary leakage from the ureter. This is a diagnosis that, although uncommon, is important for emergency physicians to know about. The literature is relatively sparse.
