ABSTRACT

Children diagnosed with cancer continue to have improved survival due to advances in effective treatment options. Increased attention is therefore now focused on quality of life issues once they are cured. Fertility preservation is of paramount concern since gonadotoxic treatments, especially radiation and chemotherapy, often impair future fertility. The importance of family counseling and having an informed discussion about the potential for treatment to impair fertility and the options available for fertility preservation is crucial. However, fertility preservation in prepubertal boys is challenging, but not impossible. Experimental methods are being investigated including cryopreservation of immature testicular tissue, xenografting, and in vitro germ cell maturation. Despite the success and relative ease of sperm banking, barriers exist and affect the number of patients offered treatment. Education and awareness of the possibilities can overcome these barriers. In this way we will continue to preserve young patients' future fertility and quality of life.

ABSTRACT

OBJECTIVE: Late-onset hypogonadism, or androgen deficiency in the aging male, is a significant cause of morbidity in older men. Many men in the low normal or equivocal range for low testosterone level exhibit signs and symptoms of hypogonadism. Serum testosterone is an imperfect maker for hypogonadism as symptoms vary greatly within the low to low normal range in addition to variations among testosterone assays. Perineal ultrasound can be effectively used to examine the bulbocavernosus muscle (BCM), an androgenized tissue that may be impacted by androgen receptor activity. METHODS: This study was a retrospective analysis of men who underwent perineal ultrasound for hypogonadism. The ultrasound data were used to calculate the area of the BCM and correlate it with indices of hypogonadismin symptomatic men including free and total testosterone and dual-energy X-ray absorptiometry (DEXA). RESULTS: The results demonstrate that there is a significant correlation between total and free testosterone and BCM area in hypogonadal patients. Comparison between BCM area and total testosterone showed R2  = 0.061 and p = 0.0187 and comparison between BCM area and free testosterone showed R2  = 0.0957 and p = 0.0034. In addition, low BCM was also correlated with DEXA results showing osteoporosis and osteopenia (R2  = 0.2239, p = 0.0027). CONCLUSION: There has been recent controversy over the safety of testosterone replacement therapy. This might be particularly important in men with hypogonadal symptoms but a low normal testosterone level. Our study investigated the use of perineal ultrasound to measure BCM as a surrogate marker for poor androgenized men presenting with hypogonadism.

ABSTRACT

Ultrasound imaging and angiography play a crucial role in the diagnosis and treatment of men with subfertility. The most commonly used imaging modality is ultrasound (US), which can be used for diagnostic purposes or to aid in treatment. Scrotal US can be used to document varicoceles in subfertile men in the context of difficult examination or for confirmation before treatment. Spectral Doppler, sonoelastography, and power Doppler have aided in the evaluation and treatment of azoospermia and oligospermia. They have proven useful in the detection of spermatogenesis and sperm retrieval. In the population with congenital Wolffian duct abnormalities, renal US can evaluate renal anomalies. In subfertile men with low ejaculate volume and oligospermia or azoospermia transrectal US can be used to evaluate and assist in treatment of ejaculatory duct obstruction. Non-US-based modalities are also commonly used in evaluating and treating men with subfertility. Magnetic resonance imaging (MRI) can be used for evaluation of pituitary adenomas in hypogonadism. More invasive imaging modalities used during treatment of subfertile men include vasography for vasal obstruction, venography and angioembolization for varicocele, and US-guided needle placement for testis-sparing surgery. Male subfertility is a complex problem and the use of imaging techniques is often essential in providing accurate diagnosis and appropriate treatment.

ABSTRACT

A complete transurethral resection of a bladder tumor (TURBT) is essential for adequately diagnosing, staging, and treating bladder cancer. A TURBT is deceptively difficult and is a highly underappreciated procedure. An incomplete resection is the major reason for the high incidence of recurrence following initial transurethral resection and thus to the suboptimal care of our patients. Our objective was to review the preoperative, intraoperative, and postoperative considerations for performing an optimal TURBT. The European Association of Urology, Society of International Urology, and The American Urological Association guidelines emphasize a complete resection of all visible tumor during a TURBT. This review will emphasize the various techniques and treatments, including photodynamic cystoscopy, intravesical chemotherapy, and a perioperative checklist, that can be used to help to enable a complete resection and reduce the recurrence rate. A Medline/PubMed search was completed for original and review articles related to transurethral resection and the treatment of non-muscle-invasive bladder cancer. The major findings were analyzed and are presented from large prospective, retrospective, and review studies.

ABSTRACT

OBJECTIVES: To study: (1) the prevalence of diurnal urinary incontinence (DI) and nocturnal enuresis (NE) in children with obstructive sleep apnea syndrome (OSAS) who underwent surgery for their upper airway symptoms, (2) the postoperative rate of enuresis resolution, and (3) factors that may predict lack of improvement post surgery. PATIENTS AND METHODS: An observational, pilot study of children 5-18 years of age with OSAS and NE who underwent tonsillectomy and/or adenoidectomy (T&A) between 2008 and 2010 was performed. Study consisted of a phone interview and chart review. Severity of NE and DI, frequency, arousal and sleeping disturbances were assessed pre and post T&A. Factors associated with failure to respond were analyzed using a logistic regression model. RESULTS: Among the 417 children who underwent T&A, 101 (24%) had NE (61 males, mean age 7.8 ± 2.5 years), and of these 24 had associated DI (6%). Mean postoperative follow-up was 11.7 months. Of the 49 whose NE responded to T&A (49%), 30 resolved within 1 month postoperatively. DI resolved in 4 children (17%). There was a statistically significant difference between responders and non-responders regarding the presence of prematurity, obesity, family history of NE, type of enuresis, enuresis severity, and ability to be easily aroused. CONCLUSION: NE was present in about one fourth of children with OSAS undergoing surgery, and resolved in about half. Lower response rate was associated with prematurity, obesity, family history of NE, presence of non-monosymptomatic NE, severe NE preoperatively, and arousal difficulties.
