Repair of a rectovesical fistula following laparoscopic radical prostatectomy with Martius fat pad flap interposition: a proposal of a new technique.

Rectovesical fistula (RVF) is defined as an abnormal communication between the rectum and the urinary bladder, most commonly after an iatrogenic injury during pelvic surgery. Patients with RVF may have various clinical presentations, ranging from fecaluria, pneumaturia, to urine leakage through the anus. The quality of life for patients with this pathology is adversely affected owing to the associated psychological burden. Surgery is the preferred treatment given the low success rates reported for conservative or minimally invasive approaches. Herein, we present a case of a 65-year-old man with RVF after radical prostatectomy successfully treated by a transperineal approach using a modified Martius procedure.

Adjustable continence therapy for severe intrinsic sphincter deficiency and recurrent female stress urinary incontinence: long-term experience.

PURPOSE: ACT was developed to treat female stress urinary incontinence resulting from intrinsic sphincter deficiency by increasing urethral resistance. We evaluated the implantation procedure and assessed patient outcomes at our center. MATERIALS AND METHODS: The adjustable continence device consists of 2 silicone balloons on either side of the proximal urethra under the bladder neck, each attached to a titanium port buried in the labia to allow postoperative titration. Urodynamic assessment was done in 57 female patients in whom previous pelvic surgery had failed. Pad use and an incontinence quality of life questionnaire were evaluated before ACT implantation, postoperatively at 1, 3, 6 and 12 months, and annually thereafter. Patients recorded the overall impression and percent of improvement postoperatively based on the Patient Global Impression Index and a visual analog scale. RESULTS: Mean followup was 72 months (range 12 to 84). At 6-year followup in 29 patients mean pad use improved from 5.6 daily at baseline to 0.41 and intrinsic sphincter deficiency improved from 27.2 to 78.6 (p <0.001). As measured on the visual analog scale, 68% of patients considered themselves dry. On the Patient Global Impression Index questionnaire 64% were very much improved, 23% were much improved and 13% were only minimally improved or unchanged. No patients considered themselves worse after the procedure. Complications necessitating device removal developed in 21.1% of patients. CONCLUSIONS: Relative ease of insertion and the ability to tailor this therapy to individual needs makes this an attractive option for the challenging treatment for recurrent stress urinary incontinence due to intrinsic sphincter deficiency.

Kidney hibernoma: case report and literature review.

OBJECTIVES: Hibernomas are rare benign tumours originating from the brown adipose tissue. They occur generally in adults with a peak incidence in the third decade and with a slightly predominance in women. They are benign tumor that does not recur with complete excision. CT and RM images should not be misdiagnosed with atypical lipomas or well-differentiated liposarcoma. We report a case of incidental renal hibernoma discovered in a 51 years old women during open surgery for kidney pielic stone. CASE REPORT: A 51-year-old woman presenting with recurrent left flank pain was diagnosed with left kidney stone. Abdomen ultrasound and i.v. pyelografy showed pyelic stone of 2 cm without other pathologies of the urinary tract. Patient underwent left percutaneus lithitripsy complicated by severe bleeding. We converted into open surgery and incidentally we observed a brown, well-defined, encapsulated, and mobile mass of 1 cm that resulted to adhere to kidney capsule. We removed this lesion respecting surgical borders. Intraoperative histological examination revealed cells with eosinofil cytoplasm and no evidence of mitosis or cellular atypia. Definitive histological examination show a well-circumscribed, encapsulated tumor, with large cells with central nuclei and multivacuolated granular cytoplasm. A rich vascular network was present absence of mitosis or atypia was confirmed. Histological diagnosis presumed hibernoma. CONCLUSION: Our case report results one of the few cases of renal localisation of hibernoma that however need a surgical treatment.

[2,8-dihydroxyadenine urolithiasis: case report and literature review]. / Calcolosi di 2,8-diidrossiadenina. Descrizione di un caso clinico e revisione della letteratura.

INTRODUCTION: 2,8-Dihydroxyadenine (DHA) urolithiasis is a rare type of urinary stone disease secondary to deficiency of adenine phosphoribosyltransferase (APRT) activity, a rare, inherited autosomal recessive disease with an incidental rate from 0.4 to 1.2%. The prevalence is higher among Japanese than other ethnic groups. APRT normally catalyzes the conversion of adenine to adenosine monophosphate and its deficiency results in 2,8-dihydroxyadenine (2,8-DHA) accumulation. This compound is extremely insoluble and its crystallization can lead to stone formation and renal failure. We report the case of 2,8-dihydroxyadenine (DHA) urolithiasis in a 52-year-old male patient. MATERIAL AND METHODS: In December 2008 a 52-year-old Caucasian man was admitted to our hospital with sudden pain in the left lumbar region. Abdominal X-ray did not show any radiopaque urinary stone. I.V. pielography showed a radiolucent left lumbar ureteral (0.6 mm) and renal (1.5 cm) stone. After therapy with tamsulosin, the ureteral stone was excreted. Successful ESWL treatment was performed for renal stone. He presented a clinical history of several episodes of bilateral renal colic and two prior ESWL treatment for radiolucent stones. Chemolitholysis was never successful. RESULTS. Stone analysis by infrared spectroscopy and microscopic examination of urine reveal typical 2,8-DHA crystals. APRT deficiency was detected in the hemolysate of erythrocyte. Partial deficiency of APRT in the patient's relatives showed heterozygosity of the enzyme defect. Allopurinol therapy successfully prevented further stone formation. 20 months later the patient remains stone free. CONCLUSION: Two types of deficit are commonly distinguished, depending on the level of residual APRT activity. Type I is complete enzyme deficiency. Type II shows residual activity in cell lysates, but enzyme activity is not demonstrable in intact cells. About 78% of the Japanese patients belong to type II. The diagnosis of the disease is based on stone analysis by infrared spectroscopy or microscopic examination of urine, which may reveal typical 2,8-DHA crystals. Molecular approach can identify mutations, which are responsible of this inherited disease. Excessive water intake, restriction of foods with high adenine contents and administration of allopurinol are useful treatments. APRT deficiency is a rare disease but we can consider this pathology in case of recurrent radiolucent stones after chemolitolysis.

[Fibromyxoid sarcoma of the kidney. A case report]. / Sarcoma fibromixoide del rene.

Low grade fibromyxoid sarcoma is an uncommon soft tissue tumor. We present the case of a 83-year-old female who developed large mass in the right kidney. A nephrectomy was performed. The tumor measured 18,5x17,5x11,5 cm and on pathology evaluation was diagnosed as low grade fibromyxoid sarcoma. Currently, the patient is doing well without evidence of local recurrence and distant metastasis. Low grade fibromyxoid sarcoma of the Kidney is a very rare tumor. The metastasizing potential is high. Sometimes long interval between tumor presentation and metastasis is observed. The treatment of choice is surgery. The role of radiotherapy and chemotherapy is uncertain.

Adjustable continence therapy for treatment of recurrent female urinary incontinence.

PURPOSE: The Adjustable Continence Therapy (ACT) device has been developed for the treatment of recurrent stress urinary incontinence resulting from intrinsic sphincter deficiency (ISD) by increasing urethral coaptation. We critically evaluated the technique and its results. METHODS: The ACT device consists of two balloons each attached to an injectable port placed in the labia majora. The port enables postoperative adjustment in balloon coaptation pressure. All 49 patients had previously failed anti-incontinence surgery. Each patient was implanted with the ACT device and assessed by preoperative and postoperative overall impression, incontinence quality of life questionnaire, and visual analog scale; 38 of the 49 subjects had a minimum of 1 year of data collected, including pad use, number of adjustments needed, and complications. RESULTS: Mean operative time was 20.3 minutes (range 10-30 minutes), with 88% of implantations performed using local or regional anesthesia. Balloon adjustments were needed in 62%; 68% of patients reported being dry and 16% improved. Complications included migration (12%), balloon failure (3.6%), and erosion (4%). CONCLUSION: The ACT device provided significant improvement in at last 70% of patients with recurrent stress urinary incontinence.

Tension-free vaginal tape versus transobturator tape as surgery for stress urinary incontinence: results of a multicentre randomised trial.

OBJECTIVES: This prospective, multicentre, randomised study compared the safety and success rate of tension-free vaginal tape (TVT) and transobturator tape (TOT) in treatment of female stress urinary incontinence. METHODS: Of 148 women, 73 were randomised to TVT and 75 to TOT. Preoperative workups included case history, clinical examination, Urogenital Distress Inventory and Impact Incontinence Quality of life questionnaires, 1-h pad test, pelvic ultrasound, and urodynamics. Intra- and postoperative complications were the primary end point; subjective and objective changes in SUI, and postoperative voiding dysfunctions were secondary end points. Patients were classified into two main categories: dry (no leakage during clinical and/or stress test and/or reported by patients) versus wet. Patients who referred being wet were separated into "improved" or "failure" on subjective analysis. Other outcome variables were quality of life questionnaires and VAS scale. Clinical checkups were conducted at 3, 6, 12 mo, and then annually. RESULTS: Both techniques are safe and no significant differences emerged in intra- and postoperative complications. At a mean follow-up of 31 mo, the overall objective cure (dry) was 71.4% for TVT and 77.3% for TOT (p=ns). When one considered "dry" plus "wet but improved," these values increased to 90% and 90.6%, respectively (p=ns). Median satisfaction rate was 9 (range: 1-10) for both procedures. Postoperative storage symptoms are a controversial issue; they persisted in 44% of patients in TVT group versus 24% in TOT group (p<0.053). CONCLUSIONS: TOT appears as safe and effective as TVT in surgery for female SUI, with minimal complications at mean follow-up of 31 mo.

Adjustable Continence Therapy for the treatment of male stress urinary incontinence: a single-centre study.

OBJECTIVE: To evaluate the Adjustable Continence Therapy (ProACT) device, a new device for the treatment of male stress urinary incontinence resulting from compromised sphincteric function. MATERIAL AND METHODS: A total of 64 males with post-prostatectomy incontinence underwent ProACT implantation. Efficacy was assessed by means of a daily pad count, a direct visual stress test, administration of the Incontinence Quality of Life (IQOL) and patient global impression (PGI) questionnaires and use of a visual analogue scale (VAS) to assess improvement in incontinence. These assessments were performed at baseline, 1, 3, 6 and 12 months after the procedure and annually thereafter. RESULTS: The pad count declined from a median of 5.2 at baseline to 2 at 6 months and to 1.54 at 12 months. The median baseline IQOL score was 31.7, and this improved to 62.5 at 6 months and to 71.1 at 12 months. In terms of postoperative daily pad usage, 43 patients (67%) were considered to be dry, 10 (15%) improved and 11 (17%) unchanged. In terms of the post operative PGI score, 42 patients (66%) considered themselves to have improved greatly, 10 (16%) to have improved quite a lot, 6 (9%) to have improved slightly and 6 (9%) to be unchanged. The average improvement based on the VAS was 80%. The average number of postoperative adjustments was three (range zero to nine). Complications included infection (2/64; 3%), erosion of balloons (5/64; 7.6%), migration (2/64; 3%) and balloon deflation (2/64; 3%). Device removal was required in 9/64 patients (14%) but was easily achieved using local anaesthesia, and this thus permitted further therapeutic intervention. New balloons were implanted following endoscopic confirmation of urethral healing. CONCLUSION: The ProACT device represents an efficacious treatment modality, which has an acceptable complication rate for a difficult group of patients.
