Vesicouterine fistula: teaching video on diagnosis and surgical treatment.

INTRODUCTION: A 42-year-old woman presented with urinary incontinence 9 years after the last of four vaginal deliveries. She had also had one Caesarean section. Immediately after the last delivery, she presented with haematuria, which resolved within a few hours, but the drain remained prophylactically for 7 days. Nine years later, she was referred to a specialist hospital. METHOD: The patient presented with continuous urinary incontinence, and physical examination revealed a loss of urine from the vagina, the latter confirmed by a methylene blue test showing loss of urine from the uterine cervix. Other diagnostic techniques used were cystography, cystoscopy and uro-CT. Based on a literature review of the management options for such patients and the relevant clinical details of our patient, a decision was made to perform a total abdominal hysterectomy and fistula repair. RESULTS AND DISCUSSION: Six months following surgery, the results were entirely satisfactory, with full urinary continence and significant improvement in the patient's quality of life. A discussion about controversial approaches to diagnosis and management is included.

PROSHADE Protocol: Designing and Evaluating a Decision Aid for Promoting Shared Decision Making in Opportunistic Screening for Prostate Cancer: A Mix-Method Study.

Background: Opportunistic prostate-specific antigen (PSA) screening may reduce prostate cancer mortality risk but is associated with false positive results, biopsy complications and overdiagnosis. Although different organisations have emphasised the importance of shared decision making (SDM) to assist men in deciding whether to undergo prostate cancer screening, recent evaluations show that the available decision aids fail to facilitate SDM, mainly because they do not consider the patients' perspective in their design. We aim to systematically develop and test a patient decision aid to promote SDM in prostate cancer screening, following the Knowledge to Action framework. Methods: (1) Feasibility study: a quantitative survey evaluating the population and clinician (urologists and general practitioners) knowledge of the benefits and risks derived from PSA determination and the awareness of the available recommendations. Focus groups to explore the challenges patients and clinicians face when discussing prostate cancer screening, the relevance of a decision aid and how best to integrate it into practice. (2) Patient decision aid development: Based on this data, an evidence-based multicomponent SDM patient decision aid will be developed. (3) User-testing: an assessment of the prototype of the initial patient decision aid through a user-testing design based on mix-methods (questionnaire and semi-structured review). The decision aid will be refined through several iterative cycles of feedback and redesign. (4) Validation: an evaluation of the patient decision aid through a cluster-randomised controlled trial. Discussion: The designed patient decision aid will provide balanced information on screening benefits and risks and should help patients to consider their personal preferences and to take a more active role in decision making. Conclusions: The well-designed patient decision aid (PDA) will provide balanced information on screening benefits and risks and help patients consider their personal preferences.

[Hand-assisted laparoscopic nephroureterectomy for the treatment of upper urinary tract transitional cancer]. / Nefroureterectomía laparoscópica mediante laparoscopia asistida por la mano para el tratamiento del carcinoma transicional del tracto urinario superior.

OBJECTIVE: To report our series of patients undergoing hand-assisted laparoscopic nephroureterectomy (HALNU) using the pluck-off procedure. MATERIALS AND METHODS: Twenty patient undergoing HALMU for upper urinary tract urothelial tumors from November 2002 to December 2007 were assessed. Demographic, clinical, surgical, and oncological data were assessed. RESULTS: Mean patient age was 69 years. Mean operating time and mean intraoperative bleeding were 176 min and 381 mL respectively. Twenty percent of patients required transfusion of blood products. Conversion to open surgery was not required in any patient. Major and minor complications occurred in 25% and 30% of patients respectively.Mean time to oral intake was 48 hours, and mean hospital stay was 5 days.Pathological study revealed transitional cell carcinoma in all cases: grade I in 5%, grade II in 60%, and grade III in 35% of patients. Clinical stage was pTa in 5%, pT1 in 20%, pT2 in 25%, pT3 in 40%, and pT4 in 10% of patients. A bladder recurrence rate of 30% and a 49% overall survival were seen after a mean follow-up of 33 months (5-73). Six-year cancer-specific survival was 67%. No patient developed either peritoneal or surgical bed recurrence. CONCLUSIONS: HALMU using the pluck-off procedure is a feasible, safe, and effective surgery. Both surgical and oncological results are similar to those of open surgery and pure laparoscopy.

[Magnetic resonance urogram as alternative to i.v. urography. Report of 3 cases. Review of the literature]. / Urograma en resonancia magnética como alternativa a la urografia i.v. A propósito de tres casos. Revisión de la literatura.

OBJECTIVES: Intravenous urography (IVU) has been classically considered as an essential examination in the great majority of urologic diseases due to the great amount of information that supplies both functional and morphological, mainly for ureteral abnormalities where other exams do not reach enough definition. Nevertheless, there are cases in which it is not possible to perform an intravenous urography due to allergy to iodine contrasts or renal failure with impossibility of contrast excretion. METHODS: We report three cases which represent the example of the indications of MRI urography as an alternative to IVU in cases in which this latter cannot or should not be performed. RESULTS: MRI urography is completely accepted as a diagnostic technique for urologic diseases as an alternative to IVU. It has advantages, such as obtaining images in multiple planes, avoiding the use of ionizing radiation, that there is no evidence of it causing cell damage, that it does not require glomerular elimination of any substance so it can be used in patients with renal failure and allergy to iodine contrasts. CONCLUSIONS: The use of MRI urography results in an advantage for patients with renal failure, iodine contrasts allergy, or greater risk of contrast nephrotoxicity as it is the case of renal transplant patients.

[Hand-assisted laparoscopic radical nephrectomy vs. open nephrectomy in the treatment of clinically localized renal cell carcinoma. Comparative study]. / Nefrectomía radical laparoscópica asistida por la mano frente a nefrectomía abierta en el tratamiento del carcinoma de células renales clínicamente localizado. Estudio comparativo.

INTRODUCTION: The description of the first laparoscopic nephrectomy made a revolution in the managing of the benign and malignant renal diseases. Hand-assisted laparoscopy (HAL) was developed with the aim of offering advantages to both patients and surgeons. The aim of the present work is to compare, in our experience, the results offered in the radical nephrectomy by HAL and open surgery, by analysis of surgical time, estimated blood loss during surgery and hospital stay. METHODS: Eleven Hand-assisted laparoscopic (HAL) radical nephrectomies and eight open radical nephrectomies were carried out at our institution during the same period (June 2001 to December 2002). All patients underwent computed tomography and were found to have a clinically localised functioning renal mass in all cases. The size of this renal mass was 4-7 cm (average 5.5 cm) in the HAL group and 4.5-15 cm (average 7.8 cm) in the open group. Patient age, body mass index, and American Society of Anaesthesiologists' score showed no significant difference between groups. RESULTS: The average surgical time in the HAL group was 156.72 minutes, the average blood loss during surgery was of 83.6 ml and the average hospital stay was of 3.09 days. Conversion to open surgery was not necessary in any patient. Average surgical time in the open surgery group was 178.25 minutes, the estimated blood loss during surgery was of 337.75 ml (p < 0.05) and the hospital stay was of 5.37 days (p < 0.05). The comparison of the means by two-tailed student's t test revealed significant differences in estimated blood loss and hospital stay, favoring HAL, and no significant differences in surgical time. CONCLUSIONS: HAL nephrectomy is feasible in almost all nephrectomies and is a safe, reproducible, and minimally invasive technique to perform extirpable renal surgery. HAL offer clear advantages over traditional open surgery, including decreased blood loss and hospital stay.

[Fatal evolution of a renal angiosarcoma]. / Evolución fatal de angiosarcoma renal.

OBJECTIVES: Report a new case of renal angiosarcoma treated by surgery and adjuvant chemotherapy with bad results. METHODS: 72-year-old male undergoing right nephrectomy for renal tumor. Pathology reports renal angiosarcoma. RESULTS: Three months after surgery patient refers lumbar pain and hemoptysis and CT scan reveals the existence of multiple bone and lung metastasis; a regimen of systemic chemotherapy with Doxorrubicine+ Ifosfamide was started without response; he died two months later. CONCLUSIONS: Primary renal angiosarcoma is very rare, with less than 10 cases in the literature before 1998, and it is always associated with bad prognosis. Diagnosis is based on immunohistochemical studies (antibodies against CD31, CD34 and factor VIII related antigen) to define the endothelial differentiation of the tumor. There is no experience to define the best therapeutic strategy against this entity.

[Controversies in the evaluation of asymptomatic microhematuria]. / Controversias en la evaluación de la microhematuria asintomática.

OBJECTIVE: Asymptomatic microhematuria continues to be a problem. It has a prevalence of 16% and numerous conditions can present this clinical manifestation. METHODS: A prospective study was carried out on all patients that consulted at the urological services during 2000 for asymptomatic hematuria. Patients presenting with irritative symptoms, urethral secretion, perineal or suprapubic pain, urinary tract infections, renal lithiasis or history of trauma were not included in the study. RESULTS: None of the patients presented tumors. Two patients presented renal lithiasis, 5 simple renal cysts, 8 hypercalciuria and 3 hyperuricosuria. None of the 11 patients with hypercalciuria or hyperuricosuria had a history of lithiasis. CONCLUSIONS: Although the size of the study is small, the incidence of tumors in patients with asymptomatic microhematuria appears to be far from the 12.5% incidence reported by some authors and might probably be closer to the 0.5% incidence reported by others. Furthermore, the significant pathology (renal lithiasis), which requires treatment, is also infrequent.
