A Novel Technique for Robotic Simple Prostatectomy: An Evolution of Retzius-sparing Technique

Urology (Gold Journal) In Press - Tue, 03/13/2018 - 00:00
To present a novel surgical concept by using the trans-Douglas approach to perform a robotic-assisted simple prostatectomy (RASP) for high-volume benign prostate hyperplasia. This transposition from oncological surgery enables performance of a better bladder neck sparing adenomectomy with good functional results.

Mucinous Lung Adenocarcinoma Metastasis to Testis in a 29 Year Old—A Case Report

Urology (Gold Journal) In Press - Tue, 03/13/2018 - 00:00
Testicular tumors represent 1% of all malignancies in men and are the most common solid tumors occurring in males between the age of 20 and 40 with the majority being primary germ cell tumors.1,2 Metastases to the testes are rare,3 and excluding lymphoma and leukemia, the commonest primary site is the prostate, followed by the lung.2,4,5 Patients with secondaries to the testes are most often over 50 years of age.3,6 We detail a rare case of a young man presenting with a testicular mass, proven to be metastasis from mucinous adenocarcinoma of the lung.

Longitudinal Rupture of Distal Corpus Cavernosum with Concomitant Urethral Injury: an Uncommon Result of a Common Mechanism

Urology (Gold Journal) In Press - Tue, 03/13/2018 - 00:00
Fracture of the penis is a well-recognized yet relatively uncommon urologic event. Forceful, blunt trauma with lateral bending of the penis in an erect state typically results in a transverse rupture of the tunica albuginea of the corpus cavernosum. Longitudinal tears of the corpus cavernosum are by themselves considered infrequent. We present a rare case of a patient with longitudinal rupture of the distal corpus cavernosum with concomitant extension to the corpus spongiosum causing partial urethral disruption as a result of trauma during sexual intercourse.

A Rare Case of Pediatric Vaginal Yolk Sac Tumor

Urology (Gold Journal) In Press - Tue, 03/13/2018 - 00:00
A 14-month-old girl was evaluated for intermittent vaginal bleeding. Vaginoscopy revealed a friable tumor, and biopsy results confirmed a yolk sac tumor. Alpha-fetoprotein was elevated (1386 ng/mL) at diagnosis but quickly normalized with chemotherapy. The patient remained tumor-free 12 months after diagnosis without the need for radical surgery. Although rare, malignant tumors of the vagina must be included in the differential diagnosis of prepubertal girls who present with vaginal bleeding. Primary yolk sac tumor of the vagina is seen in girls less than 3 years of age and is treated with chemotherapy with or without surgical excision.

Ovotesticular Disorder of Sex Development Presenting as an Acute Scrotum

Urology (Gold Journal) In Press - Tue, 03/13/2018 - 00:00
Hermaphroditism is known as ovotesticular disorder of sex development. A 14-year-old boy was admitted with right acute scrotum. Exploration revealed tunica rupture and hematoma, with no viable tissue. After one month, he was admitted again with left hemiscrotal pain. Microscopic examination of the left gonad demonstrated foci of hemorrhagic cysts, primordial follicles, and regions of seminiferous tubules. We preserved testicular tissue and the ovarian part was extracted completely. Long-term follow-up with his hormonal profile are reported.

Portal Hypertensive Vesiculopathy: A Rare Cause of Hematuria, and A Unique Management Strategy

Urology (Gold Journal) In Press - Tue, 03/13/2018 - 00:00
Portosystemic collaterals are common sequelae of portal hypertension. These often present as gastroesophageal varices. Ectopic varices can rarely be seen in duodenum, jejunum, rectum, and sites of surgical anastomoses. Bladder varices are extremely rare presenting with recurrent hematuria, with only a few reported cases. We report here management of an unusual case of hematuria managed with blood transfusion, intravenous terlipressin and endoscopic N-butyl cyanoacrylate glue injection.

Testicular tumours represent 1% of all malignancies in men and are the most common solid tumours occurring in males between the age of 20 and 40 with the majority being primary germ cell tumours (1,2). Metastases to the testes are rare (3), and excluding lymphoma and leukaemia, the commonest primary site is the prostate, followed by the lung (2,4,5). Patients with secondaries to the testes are most often over 50 years of age (3,6). We detail a rare case of a young man presenting with a testicular mass, proven to be metastasis from mucinous adenocarcinoma of the lung.

Editorial Comment

The purpose of carcinoma staging is to aggregate patients with similar clinical outcomes. T2 substaging in the TNM system has been subject to much controversy with several changes with time.1 The 8th TNM edition has now eliminated pT2 substaging entirely (references 1 and 2 in article).

Editorial Comment

Since the adoption of the 1992 AJCC/UICC TNM prostate cancer staging system incorporating a 3-tier subgrouping for pT2 along with several subsequent revisions during the years, pT2 substaging has remained controversial due to the lack of robust evidence that it adds meaningful prognostic value (reference 13 in article). In the current study Nguyen et al evaluated the oncologic outcomes of pT2a/b vs pT2c. They confirmed that all pT2 subgroups have a similar postoperative long-term oncologic outcome, thereby providing validation for a single tier pT2 entity as used in the 2017 staging system (reference 1 in article).

Editorial Comment

This study is noteworthy as the first investigation of the therapeutic role of PPD for bladder cancer. While tuberculin is derived from Mycobacterium tuberculosis, the proteins in the PPD are conserved among most mycobacterial species, including M. bovis and environmental mycobacteria. Thus, repeat PPD placement can recall existing but waned immune responses and result in positive reactions in the absence of mycobacterial infection, which is termed the boosting phenomenon. This boosting effect is maximal if the repeat PPD test is administered between 1 and 5 weeks after the first test (reference 12 in article).
