A rare Ewing-like small round cell tumor in prostate: a case report and literature review.

BACKGROUND: Small round cell tumor (SRCT) is a group of malignancy with similar optical microscopic morphology. Despite its low incidence, SRCT has a high malignant degree and poor prognosis. Besides, atypical clinical symptoms make it difficult in preoperative diagnosis. CASE REPORT: A 67-year-old man was presented to the outpatient service with dysuria and weak urine stream lasting for 3 months. After oral treatment with tamsulosin and finasteride for 2 months, the symptoms worsen. Transurethral prostate holmium laser enucleation was operated and postoperative pathology result revealed small blue round cell malignant tumor. Further immunohistochemistry and fluorescence in situ hybridization examination indicated Ewing-like SRCT. So a Da Vinci Robotic prostatectomy was performed further and whole-genome sequencing was conducted. Several gene mutations including RAF1, ARID1A, SMARCA4, and BCL2L11 were found but no FDA-approved drug could treat specifically. Then the patient received Ewing-type therapeutic regimens treatment and has been followed up to date (over 24 months). CONCLUSION: Because of its non-elevated serum PSA level, prostate SRCT is often ignored as a possibility of malignant tumor and regarded as benign prostatic hyperplasia (BPH). The possibility of prostate SRCT need to be considered if dysuria symptoms could not alleviate significantly after a period of oral treatment.

Lasers for pelvic floor dysfunctions: is there evidence?

PURPOSE OF REVIEW: The purpose of this review is to discuss the available energy sources used in the vaginal canal that are currently being promoted for certain pelvic floor conditions and explore the body of peer-reviewed literature supporting their use. RECENT FINDINGS: The majority of research has focused on the use of fractional CO2 laser treatment for genitourinary syndrome of menopause (GSM). Most of these studies are nonrandomized prospective studies, but their data consistently shows an improvement in symptoms without significant side effects. SUMMARY: Vaginal laser treatment for GSM is of particular interest to gynecologists as it provides patients with a history of estrogen receptor positive breast cancer, thromboembolic event, or other contraindication to hormone therapy, an effective treatment option. Currently, we are in the early stages of scientific investigation into the use of lasers in the treatment of pelvic floor dysfunction, but the emerging data is encouraging. The existing data is limited to mostly observational studies with additional quality randomized controlled trials and sham studies needed to ensure that physicians are providing the optimum evidence-based treatments to their patients. At the present time there is insufficient data to promote these therapies for stress incontinence, vaginal tightening, or other pelvic floor abnormalities.

Use of a novel fractional CO2 laser for the treatment of genitourinary syndrome of menopause: 1-year outcomes.

OBJECTIVES: To assess safety and efficacy of a fractional CO2 laser therapy for the treatment of genitourinary syndrome of menopause (GSM) with follow-up to 1 year posttreatment. METHODS: Women presenting with GSM and meeting inclusion criterion were enrolled. Visual Analog Scales were used to grade vaginal pain, burning, itching, dryness, dyspareunia, and dysuria. Dilators were used to rate vaginal elasticity at baseline and at each follow-up visit. Before each treatment and at follow-up, Vaginal Health Index scoring and Female Sexual Function Index questionnaires were completed. Women received three vaginal laser treatments spaced 6 weeks apart. Participant satisfaction was measured on 5-point Likert scales (1 = very dissatisfied, 5 = very satisfied). RESULTS: Of 30 women (mean age 58.6 ±â€Š8.8 years), three were lost to follow-up at 3 months and six at 1 year. None were discontinued or withdrew due to an adverse event. Average improvement in Visual Analog Scale scores for all symptom categories was statistically significant at 3 months and remained so through 1 year, except dysuria. Differences between data at 3 months and 1 year were not statistically significant, indicating persistence of positive outcomes. Average overall improvement in pain was 1.9 (±3.4), burning 1.9 (±3.1), itching 1.4 (±1.9), dryness 5.9 (±2.8), dyspareunia 4.9 (±3.3), and dysuria 0.9 (±3.1). Improvement in average Vaginal Health Index and Female Sexual Function Index scores was also statistically significant (P < 0.0001). Of 19 women undergoing dilator examination at 1 year, 18 (94.8%) were comfortable with the same or larger dilator size. Twenty-two of 24 women (92%) were satisfied or extremely satisfied with the treatment at 1 year. CONCLUSIONS: Based on study data up to 1 year, the fractional CO2 laser may be an effective and safe treatment for women suffering from symptoms of GSM, although additional studies with larger populations and placebo control is needed to confirm these results.

[VIRAL INFECTIONS: HUMAN PAPILLOMAVIRUS AND GENITAL HERPES TYPE 1 AND TYPE 2 AS A CAUSE OF CHRONIC RECURRENT CYSTITIS WITH SEVERE DYSURIA IN WOMEN WITH URETHRAL HYPERMOBILITY AND HYPOSPADIAS].

Female hypospadias presenting as a misplaced urethral opening is a common cause of chronic recurrent cystitis. Cystitis occurs when urogenital infection and anaerobic bacteria enter the urethra and bladder from the vagina. The authors argue that chronic infections of the lower urinary tract in women with hypospadias should be treated surgically by meatal transposition. They present a study confirming the role of the antiviral drug Panavir in prevention of inflammatory complications in the postoperative period in patients with a history of viral infection (human papillomavirus and herpes).

Presentation, Endoscopic Management, and Significance of Hemostatic Clip Migration into the Lower Urinary Tract Following Radical Prostatectomy.

OBJECTIVES: Hemostatic clip migration into the lower urinary tract is a potential complication of radical prostatectomy that may cause symptoms, anxiety, and functional concern. Our objective was to evaluate initial presentation, endoscopic management, and outcomes of patients with hemostatic clip migration following radical prostatectomy. PATIENTS AND METHODS: We retrospectively identified all patients with hemostatic clip migration at our institution from 1977 to 2012. Patient records were then reviewed to identify causative factors, presentation, and long-term functional outcomes. RESULTS: Seventeen patients were identified with clip migration following radical prostatectomy. Eight (47%) patients had undergone open retropubic radical prostatectomy, and 9 (53%) had received robot-assisted radical prostatectomy. Hemostatic clip migration was diagnosed at a median of 8 (range, 1-252) months after prostatectomy. The majority of patients (n = 16, 94%) were symptomatic upon the diagnosis of clip migration. Symptoms included irritative urinary symptoms (n = 14, 82%), perineal pain (n = 3, 18%), hematuria (n = 2, 12%), and infection (n = 2, 12%). Five (29%) had concomitant bladder neck contracture. Fifteen (88%) underwent successful endoscopic clip removal, whereas 2 (13%) patients required a repeat operation for recurrent clip erosion. With a median follow-up of 1.6 years, the majority (n = 13, 87%) had complete symptom resolution after clip removal, although 2 patients had recurrent bladder neck contracture. CONCLUSIONS: Hemostatic clip migration after prostatectomy is often symptomatic with irritative voiding complaints, perineal pain, hematuria, infection, or bladder neck contracture. Fortunately, clips can be removed endoscopically with expected symptom resolution in the vast majority of patients.

Forgotten long-term indwelling double "J" stent.

A poor, uneducated patient from a rural background presented to us with burning micturition and colicky pain in the loin. He had undergone surgery for pelvi-ureteric junction (PUJ) obstruction on the right side four years earlier. Following surgery, the patient was irregular in his follow-up and, as such, he did not get the double "J" (DJ) stent, which was placed during surgery, removed. Ultrasonography performed during the present admission revealed mild hydronephrosis of the right kidney with a tiny calculus in the urinary bladder. Intravenous urography revealed mild hydronephrosis with the DJ stent in situ in the right kidney. After an unsuccessful attempt with cystoscopy, the stent was removed successfully by suprapubic cystostomy. The post-operative course was uneventful and the patient was discharged in seven days.

Stone cobras: adult bilateral single system ureteroceles presenting with multiple calculi.

25-year-old previously healthy male presented with dysuria and bilateral flank pain. Abdominal radiography and computed tomography revealed bilateral orthotopic ureteroceles with significant calculi. Bilateral endoscopic ureterocele incision and ureteroscopy were used for complete stone clearance. Symptoms resolved after treatment, and follow-up voiding cystourethrogram performed at 3 months revealed no evidence of vesicoureteral reflux. Adult orthotopic bilateral ureteroceles with calculi is a rare clinical entity amenable to endoscopic management.

[Two-years follow-up of radiofrequency thermotherapy for urination disorders due to benign prostatic hyperplasia]. / Résultat à deux ans de la thermothérapie prostatique par radiofréquence pour troubles mictionnels liés à l'HBP.

AIM: To describe medium-term functional results of Transurethral Needle Ablation (TUNA) to treat symptomatic benign prostatic hyperplasia (BPH) refractory to medical treatment. MATERIALS AND METHOD: Patients who completed at least 2 years follow-up after TUNA were systematically offered a reevaluation including: Flowmetry, PSA, symptom score (IPSS), satisfaction index visual analogic scale (VAS) and a treatment impact evaluation with a Likert scale (ranging from much worse to much improved). RESULTS: From December 2002 to January 2007, 45 patients were treated with TUNA under local regional anaesthesia (prostatic block). Twenty-seven of them were followed-up longer than 24 months (median follow-up 44 months [26-52]). Changes in the selected outcomes were: increase in Qmax from 9.5 mL/s preoperatively to 9 mL/s at 6 month and 11.5 mL/s after 2 years; increase in IPSS from 19.3 before TUNA to 16.3 at 6 month and 16.5 after 2 years. About subjective evaluation, 58% of patient gave a satisfaction VAS>or=6, and the improvement index was greater or equal to +1 in 67% of case. CONCLUSION: In this initial monocentric experiment, despite a modest improvement of objective parameters and a 20% of retreatment rate, TUNA give contentment and improvement sensation for 60% of patients who were treated for non-efficiency of medical treatment for benign prostatic hyperplasia.

Cowper's duct ligation for treatment of dysuria associated with Cowper's syringocele treated previously with transurethral unroofing.

A Cowper's duct cyst is a rare entity that occurs most commonly in young men. The current urologic literature supports management with a transurethral unroofing procedure. For patients who present with persistent symptoms associated with a Cowper's syringocele status post-transurethral unroofing, transperineal ligation of the Cowper's duct may be of value in alleviating the symptoms.

A pilot study to evaluate the clinical relevance of endometriosis-associated nerve fibers in peritoneal endometriotic lesions.

OBJECTIVE: To investigate the clinical relevance of endometriosis-associated nerve fibers in the development of endometriosis-associated symptoms. DESIGN: Prospective nonrandomized study. SETTING: University hospital endometriosis center. PATIENT(S): Fifty-one premenopausal patients underwent surgical laparoscopy because of chronic pelvic pain, dysmenorrhea, or for ovarian cysts. Endometriosis was diagnosed in 44 patients. INTERVENTION(S): The preoperative and postoperative pain scores were determined using a standardized questionnaire with a visual analogue scale from 1-10. Patients with peritoneal endometriosis were divided into two groups depending on their preoperative pain score: group A with a pain score of at least 3 or more and group B with a pain score of 2 or less. Patients without peritoneal endometriosis were classified as group C and patients without endometriosis were classified as group D. Immunohistochemical analysis of neurofilament and protein gene product 9.5 were used for nerve fiber detection. Occurrence of endometriosis-associated nerve fibers was correlated with the severity of pelvic pain and/or dysmenorrhea. RESULT(S): Peritoneal endometriosis-associated nerve fibers were found significantly more frequently in group A than in group B (82.6% vs. 33.3%). CONCLUSION(S): The present study suggests that the presence of endometriosis-associated nerve fibers in the peritoneum is important for the development of endometriosis-associated pelvic pain and dysmenorrhea.

A case of nerve root heat injury induced by percutaneous laser disc decompression performed at an outside institution: technical case report.

OBJECTIVE: In recent years, percutaneous laser disc decompression (PLDD) has become a routine surgical procedure because it can be performed under local anesthesia and is minimally invasive. However, there is a risk of nerve root and endplate injury owing to heat generated by laser irradiation during PLDD. We recently performed salvage surgery on a patient with heat injury to the L5 nerve root that developed after PLDD. CLINICAL PRESENTATION: One month before presenting to our hospital, the patient underwent two sessions of PLDD for lumbar vertebral disk herniation at another institution. The patient developed worsening sciatica, as well as bowel and urinary problems after the PLDD. INTERVENTION: We performed salvage surgery after PLDD. The intraoperative findings in the present case included carbon spots in the dura mater of the nerve root and a disc herniation strongly adherent to the nerve roots. These findings indicate that the area adjacent to the nerve roots was damaged by excessive heat during laser irradiation. CONCLUSION: When salvage surgery is performed after a PLDD procedure, disc and nerve root injuries owing to laser heat energy must be considered.

Dysgeusia related to urinary obstruction from benign prostatic disease: a case control and qualitative study.

Anecdotal reports suggest that dysgeusia may be related to a variety of systemic factors, including bladder outflow obstruction. This is a hospital-based case-controlled study involving 111 patients who were admitted to urological wards for transurethral resection of the prostate for benign prostatic disease with age- and sex-matched control of 137 subjects. We used a semi-structured questionnaire by a trained interviewer at admission (preoperative), at the postoperative period and at follow-up between 4-6 months (median 5 months). Analysis used unpaired t-test and chi(2) test. The incidence of dysgeusia was 22% in the study group and 13% in the control group (P=N.S.). However, strikingly, the dysgeusia in the study group was relieved promptly by relief of urinary obstruction in 100% of cases and did not return within the follow-up period. The mechanism of the dysgeusia associated with dysuria in benign prostatic disease is unknown, but we suggest that the dysgeusia could be from the stress of dysuria or due to a release of an unknown chemical from the urinary tract or an overflow of neural impulse from pontine/cortical micturition centres to the taste centres. An association between dysgeusia and dysuria has not been described before.
