Adrenal Crest in Testicular Tissue of an Undescended Testis in an Adult Patient: A Case Report.

This case report describes a rare occurrence of ectopic adrenal cortical tissue (EACT) in the undescended testis (UDT) of an adult male patient. The patient presented with an empty left scrotum since birth, and a magnetic resonance imaging (MRI) confirmed the diagnosis of left-side UDT. Orchidectomy was performed, and a microscopic examination revealed a UDT with EACT. The patient had no significant medical or surgical history and had a normal preoperative hormonal profile. EACT is usually found incidentally during surgical procedures and is more common in children than adults. This case emphasizes the importance of investigating adrenal rests due to the potential of neoplastic transformation or hormonal activity. The case report concludes that EACT of the UDT is still a possibility in the adult patient population.

Development of a Prostatic Urethral Cyst After Rezum Causing Persistent Lower Urinary Tract Symptoms.

Water vapor thermal therapy (WVTT) is a new modality. There are just a few short periods of outcome surveillance following Rezum, with a maximum term of five years. The majority of side effects are irritative lower urinary tract symptoms caused by endoscopic manipulation and typically last a short time. Herein, we present a novel case of a 71-year-old male patient with a Rezum-induced prostatic urethral cystic lesion. Five months following Rezum, an ultrasound was performed to evaluate persistent lower urinary tract symptoms (LUTS) revealed the lesion. The patient preferred conservative management rather than cystoscopy and ablation of prostatic urethral cyst.

Imaging findings of atypical leiomyoma of urinary bladder simulating ureterocele.

Bladder leiomyomas are relatively rare benign tumors of the bladder. They represent <0.5% of all urinary bladder tumor. In the literature, only about 250 cases reported worldwide. They are commonly found in middle-aged females. Patients present with variety of clinical presentations with predominance of obstructive urinary symptoms. Ultrasound bladder is the first preferable diagnostic tool. Definitive diagnosis is made by histopathological examination. Surgical excision is almost highly effective, leaving a low recurrence rate. We report a 34-year-old male who presented with complaints of dysuria and incomplete voiding. Ultrasound showed a cystic fluid-filled bladder mass (ureterocele), which was excised through a transurethral resection. The histopathologic diagnosis was bladder leiomyoma.

Targeted focal therapy for the management of organ confined prostate cancer.

PURPOSE: Patients currently diagnosed with low risk prostate cancer are often overtreated and experience complications, resulting in detriment to quality of life. Targeted focal therapy is a minimally invasive procedure designed to ablate tumor foci while minimizing collateral damage to maintain quality of life. MATERIALS AND METHODS: This institutional review board approved, prospective study was done to assess the safety and efficacy of targeted focal therapy using cryotherapy in men 40 to 85 years old diagnosed with low risk, organ confined prostate cancer at our institution between 2006 and 2009. Low risk, organ confined prostate cancer was defined as Gleason score 7 or less (3 + 4) on transrectal ultrasound biopsy, tumor burden 50% or less and prostate specific antigen less than 10 ng/dl. Patients were evaluated for eligibility after undergoing 3-dimensional mapping biopsy. Median followup was 28 months (IQR 26-31). RESULTS: A total of 62 men with low risk disease met study inclusion criteria. At 1 year biopsy was negative in 50 of 62 patients (81%). All 12 men who tested positive on repeat biopsy had a Gleason score of 3 + 3 = 6 with 1 or 2 positive cores. The median prostate specific antigen change was a 3.0 ng/dl decrease (p <0.01). The median American Urological Association symptom score change was a 1.5-point decrease (p <0.01). No significant change was observed in Sexual Health Inventory for Men score (p = 0.6). No urinary incontinence episodes and no severe side effects were noted. CONCLUSIONS: Targeted focal therapy in carefully selected patients provides a feasible, practical option for treating low risk prostate cancer with minimal impact on quality of life.

The accuracy of prostate cancer localization diagnosed on transrectal ultrasound-guided biopsy compared to 3-dimensional transperineal approach.

Background. Prostate cancer is often understaged following 12-core transrectal ultrasound- (TRUS-) guided biopsies. Our goal is to understand where cancers are typically missed by this method. Methods. Transperineal 3-dimensional mapping biopsy (3DMB) provides a more accurate depiction of disease status than transrectal ultrasound- (TRUS-) guided biopsy. We compared 3DMB findings in men with prior TRUS-guided biopsies to determine grade and location of missed cancer. Results were evaluated for 161 men with low-risk organ confined prostate cancer. Results. The number of cancer-positive biopsy zones per patient with TRUS was 1.38 ± 1.21 compared to 3.33 ± 4.06 with 3DMB, with most newly discovered cancers originating from the middle lobe and apex. Approximately half of all newly discovered cancerous zones resulted from anterior 3DMB sampling. Gleason upgrade was recognized in 56 patients using 3DMB. When both biopsy methods found positive cores in a given zone, Gleason upgrades occurred most frequently in the middle left and right zones. TRUS cancer-positive zones not confirmed by 3DMB were most often the basal zones. Conclusion. Most cancer upgrades and cancers missed from TRUS biopsy originated in the middle left zone of the prostate, specifically in anterior regions. Anterior sampling may lead to more accurate diagnosis and appropriate followup.

Current Challenges in Prostate Cancer Management and the Rationale behind Targeted Focal Therapy.

Among men, prostate cancer has a high prevalence, with relatively lower cancer-specific mortality risk compared to lung and colon cancer. Prostate-specific antigen (PSA) screening has increased prostate cancer awareness since its implementation as a screening tool almost 25 years ago, but, due to the largely indolent course of this disease and the unspecific nature of the PSA test, increased incidence has largely been associated with cancers that would not go on to cause death (clinically insignificant), leading to an overdiagnosis challenge and an ensuing overtreatment consequences. The overtreatment problem is exacerbated by the high risk of side effects that current treatment techniques have, putting patients' quality of life at risk with little or no survival benefit. The goals of this paper are to evaluate the rise, prevalence, and impact of the overdiagnosis and ensuing overtreatment problems, as well as highlight potential solutions. In this effort, a review of major epidemiological and screening studies, cancer statistics from the advent of prostate-specific antigen screening to the present, and reports on patient concerns and treatment outcomes was conducted to present the dominant factors that underlie current challenges in prostate cancer treatment and illuminate potential solutions.

The role of targeted focal therapy in the management of low-risk prostate cancer: update on current challenges.

Prostate cancer is one of the most prevalent cancers among men in the United States, second only to nonmelanomatous skin cancer. Since prostate-specific antigen (PSA) testing came into widespread use in the late 1980s, there has been a sharp increase in annual prostate cancer incidence. Cancer-specific mortality, though, is relatively low. The majority of these cancers will not progress to mortal disease, yet most men who are diagnosed opt for treatment as opposed to observation or active surveillance (AS). These men are thus burdened with the morbidities associated with aggressive treatments, commonly incontinence and erectile dysfunction, without receiving a mortality benefit. It is therefore necessary to both continue investigating outcomes associated with AS and to develop less invasive techniques for those who desire treatment but without the significant potential for quality-of-life side effects seen with aggressive modalities. The goals of this paper are to discuss the problems of overdiagnosis and overtreatment since the advent of PSA screening as well as the potential for targeted focal therapy (TFT) to bridge the gap between AS and definitive therapies. Furthermore, patient selection criteria for TFT, costs, side effects, and brachytherapy template-guided three-dimensional mapping biopsies (3DMB) for tumor localization will also be explored.
