PURPOSE: Primary urethral carcinoma (PUC) has an aggressive natural history; however, controversy exists regarding the role of multimodal therapy for its treatment. Our objective was to examine practice patterns and survival outcomes for locally advanced urethral cancers. METHODS: The National Cancer Database was queried for patients with T2-4 or N1-2M0 PUC with urothelial, squamous, or adenocarcinoma histology from 2004 to 2013. Temporal trends for receipt of local or definitive surgery, radiotherapy (XRT), and systemic therapy were assessed...

The management of penile cancer has altered dramatically over the last decade. Confidence to excise lesions safely with smaller margins has led to the adoption of penile-preserving techniques and in turn improved the functional and cosmetic results. Patients undergoing partial penectomy (PP) find that the urethral meatus is located in an abnormal ventral position. In addition, there is a high risk of meatal stenosis. We describe our novel technique that allows the urethral meatus to be centralised after PP and creation of a pseudo-glans and wide meatus and therefore maintain the cosmetic appearance of the penis after split thickness skin grafting...

The aim of this review is to examine all urethral strictures and stenoses subsequent to treatment for prostate cancer, including radical prostatectomy (RP), radiotherapy, high intensity focused ultrasound (HIFU) and cryotherapy. The overall majority respond to endoscopic treatment, including dilatation, direct visual internal urethrotomy (DVIU) or bladder neck incision (BNI). There are adjunct treatments to endoscopic management, including injections of corticosteroids and mitomycin C (MMC) and urethral stents, which remain controversial and are not currently mainstay of treatment...

BACKGROUND: Anastomotic leakage (AL) is one of the most dreadful postoperative complications because it can result in increased morbidity and mortality as well as poorer long-term prognosis. Although most studies of AL limited their investigation time to a period of 30 days postoperatively, only a few studies have shown that AL can occur after that period. Here, we report four patients of rectal cancer with delayed AL following laparoscopic intersphincteric resection (ISR) and conduct a literature review on delayed AL...

OBJECTIVE: Lower urinary tract symptoms (LUTS) are common following radical prostatectomy (RP) or intended curative radiotherapy in prostate cancer patients. One-quarter of those treated with RP experience biochemical failure and are subsequently offered salvage radiotherapy (SRT) to the prostatic bed. The aim of this study was to elucidate long-term LUTS after surgery and SRT. MATERIALS AND METHODS: Urodynamic parameters from 16 patients treated with RP and subsequent SRT in the period 2000-2010 were evaluated with uroflowmetry, filling cystometry, pressure-flow and urethral pressure profile (UPP)...

PURPOSE: Post-implant CT-scanning is an essential part of permanent prostate brachytherapy. However, the evaluation of post-implant CT dosimetry is not straightforward due to the edema that can modify the dose to the prostate and to the organs at risk. The aim of this study is to evaluate the impact of the timing of the post-implant CT-scan on the dosimetric results and to verify if the Day 0 scan findings can predict Day 50 scanning. METHODS: 136 consecutive patients who received monotherapy with I-125 implants were selected for this study...

BACKGROUND: To investigate mechanisms underlying our previous observation of a large rise in serum prostate-specific antigen, a marker of prostate pathology, during both sexually transmitted and systemic infections, we measured serum high-sensitivity C-reactive protein (hsCRP), a marker of systemic inflammation, in our previous case-control study of young, male US military members and compared our findings to those for PSA. METHODS: We measured hsCRP before and during infection for 299 chlamydia, 112 gonorrhea, and 59 non-chlamydial, non-gonococcal urethritis (NCNGU) cases; before and after infection for 55 infectious mononucleosis (IM) and 90 other systemic/non-genitourinary cases; and for 220-256 controls...

PURPOSE: To evaluate the impact of incontinence etiology on artificial urinary sphincter (AUS) device outcomes. MATERIALS AND METHODS: We identified 925 patients who underwent primary AUS placement from 1983 to 2011. The etiology of incontinence was categorized as radical prostatectomy alone, radical prostatectomy with radiation, benign prostate resection, and those with cryotherapy as a salvage prostate cancer treatment. Hazard regression and competing risk analyses were used to determine the association of the etiology of incontinence with device outcomes...

BACKGROUND: We assessed the change in LUTS after prostate brachytherapy to reveal factors for prolonged urination disorder. MATERIALS AND METHODS: Four hundred and four patients received prostate brachytherapy at our institution and were followed-up for at least 2 years. We evaluated the correlation of mean IPSS changes and clinical factors. Using multivariate analysis, we also evaluated clinical factors with potential to delay IPSS resolution. RESULTS: In cases with prostate volume more than 30 cm(3), radiation dose to 90% of prostate volume (D90) more than 160 Gy, and radiation dose to 30% of the urethral volume (UD30) more than 240 Gy, mean IPSS levels were significantly higher, even 30 months after treatment...

BACKGROUND AND PURPOSE: Intraoperative transrectal ultrasound dosimetry during low-dose-rate prostate brachytherapy is imprecise due to sonographic distortion caused by seed echoes and needle tracks that obscure seed positions or create false signals as well as traumatic edema. Here we report the results of a pilot study comparing a combined ultrasound and fluoroscopy-based seed localization method (iRUF) to standard ultrasound-based dosimetry (USD). MATERIAL AND METHODS: Eighty patients undergoing permanent Pd-103 seed implantation for prostate cancer were prospectively enrolled...

Numerous environmental factors such as diet, alcohol use, stress, and environmental chemicals are known to elicit epigenetic changes, leading to increased rates of cancers and other diseases. The incidence of head and neck cancer, one of the most common cancers in Taiwanese males, is increasing: oral cancer and nasopharyngeal carcinoma are ranked fourth and tenth respectively, among the top ten cancers in this group, and a major cause of cancer-related deaths in Taiwanese males. Previous studies have identified smoking, alcohol use, and betel quid chewing as the three major causes of head and neck cancers; these three social habits are commonly observed in Taiwanese males, resulting in an increasing morbidity rate of head and neck cancers in this population...

OBJECTIVE: To determine if age is an independent predictor of surgical success in patients undergoing urethroplasty. Urethroplasty performed by excision and primary anastomosis depends on vascular collateralization. Successful augmented urethroplasty depends on graft neovascularization. Older patients have more comorbid conditions including peripheral vascular disease associated with reduced penile blood flow. MATERIALS AND METHODS: A retrospective review of urethroplasties from 11 institutions...

BACKGROUND: Urethral cancer is a rare malignancy, representing <1% of all malignancies. Optimal management, due to its rarity, presents as a treatment dilemma for physicians. There is a lack of consensus regarding treatment as large randomized trials cannot be performed; thus, optimal management decisions rely on study of retrospective cases. This is a review of our institutional experience with urethral cancer treated with various treatment modalities. METHODS: A retrospective chart review was performed on 31 patients treated for primary cancer of the urethra from 1958 to 2008...
