Delivery of a urology online course using Moodle versus didactic lectures methods.

PURPOSE: To subjectively and objectively compare an accessible interactive electronic library using Moodle with lectures for urology teaching of medical students. METHODS: Forty consecutive fourth-year medical students and one urology teacher were exposed to two teaching methods (4 weeks each) in the form of problem-based learning: - lectures and - student-centered group discussion based on Moodle (modular object-oriented dynamic learning environment) full time online delivered (24/7) with video surgeries, electronic urology cases and additional basic principles of the disease process. RESULTS: All 40 students completed the study. While 30% were moderately dissatisfied with their current knowledge base, online learning course delivery using Moodle was considered superior to the lectures by 86% of the students. The study found the following observations: (1) the increment in learning grades ranged from 7.0 to 9.7 for students in the online Moodle course compared to 4.0-9.6 to didactic lectures; (2) the self-reported student involvement in the online course was characterized as large by over 60%; (3) the teacher-student interaction was described as very frequent (50%) and moderately frequent (50%); and (4) more inquiries and requisitions by students as well as peer assisting were observed from the students using the Moodle platform. CONCLUSIONS: The Moodle platform is feasible and effective, enthusing medical students to learn, improving immersion in the urology clinical rotation and encouraging the spontaneous peer assisted learning. Future studies should expand objective evaluations of knowledge acquisition and retention.

Long-Term Results of Anderson-Hynes Pyeloplasty in Children: How Long Follow-Up Is Necessary?

PURPOSE: After a successful pyeloplasty at 3 to 6 months, the question remains whether children need a long follow-up. METHODS: The medical charts of patients with long-term follow-up (> 5 years), who underwent dismembered pyeloplasty for uretero-pelvic junction obstruction (UPJO) from May 1998 to May 2007, excluding those with bilateral UPJO, solitary kidney, associated vesicoureteral reflux or other abnormalities, and inconclusive renogram due to poor renal function, were retrospectively reviewed. Ultrasonography, differential renal function (DRF, DMSA), and renal drainage on diuretic renography (diethylene-triamine-pentaacetate technetium-99 or DTPA-Tc99) were performed at 3 and 6 months every year. RESULTS: Complete data were available for 28 consecutive patients (28 renal unities) with 2 months to 12 years (mean age, 2.4 years) at surgery, of whom 21 (75%) were boys, 17 diagnosed prenatally (61%) and 18 unities (64.3%) were left, with median follow-up of 10.7 years. Images were graded according to the Society for Fetal Urology grading system: Grade III in 11 (49%) and grade IV in 17 (61%). All cases presented > 10% DRF (DMSA) and obstructed DTPA-Tc99. The T1/2 (the half-time of drainage) less than 20 minutes at 3 months was found in 21 cases (75%) and less than 25 minutes in 7 cases (25%). Renal function and patency were maintained during follow-up for all units with 8% maximum fluctuation of DRF. One index case (3.6%) of renal function deterioration presented DRF fluctuation > 8% at 3 months (from 23 to 32%) and progressive hydronephrosis and indeterminate DTPA at 6 months. CONCLUSIONS: Satisfactory diuretic renogram at 3 to 6 months after pyeloplasty with maintained renal function and stable hydronephrosis suggests no need for further follow-up and indicates no functional loss with time. More than 8% DRF fluctuation might be a significant cutoff for further intervention aiming nephron preservation.

Diethylstilbestrol 1 mg in the Treatment of Acute Urinary Retention due to Prostatic Obstruction in the Elderly: A Preliminary Study.

Patients who failed a catheter-free trial after acute urinary retention and one week of full dose alpha-blocker and 5-alpha-reductase inhibitor were offered Diethylstilbestrol 1 mg plus Aspirin 100 mg over 4 weeks. Prostate volume, age, serum creatinine, and initial retention drained urine volume were recorded. After excluding cardiovascular morbidity (n = 7), upper urinary tract dilation (n = 3), compromised renal function (n = 2), urinary tract infection (n = 2), neurological diagnosis (n = 2), or preferred immediate channel transurethral resection of prostate (n = 5), 48 of 69 consecutive patients ≥70 years were included. Mean age was 76.6 years (70-84), mean prostate volume 90 cm(3) (42-128), and mean follow-up 204 days; 58% (28/48) were passing urine and 42% (20/48) were catheter dependent after 4 weeks Diethylstilbestrol trial. Mean age and drained urine volume of catheter dependent patients were 82.4 years and 850 mL compared with 74.6 years and 530 mL in catheter-free men, respectively. Age and drained urine volume were independent predictors of catheter-free trial (both P < 0.01). Seventy-five percent (6/8) of patients 80 years and older were catheter dependent. Transient nipple/breast tenderness and gynecomastia were the only adverse effects reported by 21% (10/48) and 4% (2/48), respectively. No patient presented severe complications.

Digital rectal examination standardization for inexperienced hands: teaching medical students.

Objectives. To standardize digital rectal examination (DRE) and set how it correlates with the comprehensive evaluation of lower urinary tract symptoms (LUTS). Methods. After scaled standardization of DRE based on fingertips graphical schema: 10 cubic centimeters-cc for each fingertip prostate surface area on DRE, four randomly selected senior medical students examined 48 male patients presenting with LUTS in an outpatient clinical setting, totaling 12 DRE each. Standardized DRE, international prostate symptom score (IPSS), serum PSA, transabdominal ultrasound (US), urodynamic evaluation, and postvoid residue were compared. Results. The mean and median PVs were US-45 and 34.7 cc (5.5 to 155) and DRE-39 and 37.5 cc (15 to 80). Comparing DRE and US by simple linear regression: US PV = 11.93 + 0.85 × (DRE PV); P = 0.0009. Among patients classified as nonobstructed, inconclusive, and obstructed, the US PVs were 29.8, 43.2, and 53.6 cc (P = 0.033), and DRE PVs were 20, 35, and 60 cc (P = 0.026), respectively. Conclusion. This is the first attempt to DRE standardization focusing on teaching-learning process, establishing a linear correlation of DRE and US PVs with only 12 examinations by inexperienced hands, satisfactorily validated in an outpatient clinical setting.

Comparative, prospective, and randomized study between urotherapy and the pharmacological treatment of children with urinary incontinence.

OBJECTIVE: To verify and compare the results of behavioral modification plus pelvic floor muscle training and behavioral modifications plus oxybutynin chloride in children with nonmonosymptomatic enuresis. METHODS: A total of 47 children were randomized using opaque and sealed envelopes sequentially numbered. Group I was composed of 21 children who underwent antimuscarinic treatment (oxybutynin), and Group II was composed of 26 patients who underwent pelvic floor muscle training. Both groups were instructed as to behavioral modifications. RESULTS: The voiding diary results were compared each month between Groups I and II. In the first month of treatment, children in Group I presented 12.2 dry nights, 13.4 in the second month, and 15.9 in the last month. In Group II, the results were: 14.9 dry nights in the first month, 20.8 dry nights in the second and 24.0 dry nights in the last month. There was a significant difference between the groups in second and third months. CONCLUSION: Pelvic floor exercises associated with behavioral changes were more effective than pharmacological treatment in children with urinary incontinence.

No Grupo II, os resultados foram: 14,9 noites secas no primeiro mês, 20,8 no segundo mês e 24,0 no último mês. Houve diferença significativa entre os grupos no segundo e no terceiro mês. CONCLUSÃO: Os exercícios do assoalho pélvico associados a mudança comportamental foram mais efetivos do que o tratamento farmacológico em crianças com incontinência urinária.

Seminoma espermatocítico associado a rabdomiossarcoma de testículo / Spermatocytic seminoma associated with rhabdomyosarcoma of the testis

The authors present a rare case of spermatocytic seminoma associated to rhabdomyosarcoma of the testicle. The anatomopathological examination after radical left orchiectomy revealed cells that are characteristics of rhabdomyosarcoma. The diagnosis was confirmed by an immunohistochemical study that showed as stron positive for specific muscle actin (HHF35) and sarcomeric actin. In other areas of the tumor, there were cells resembling seminoma, some of them more voluminous and with spermatocyte characteristics, leading to a diagnosis of spermatocytic seminoma. During staging examinations, the patient shown a retroperitoneal lymphadenomegaly in the computed tomography scan and was submitted to 3 cycles of polichemotherapy with cisplatin, etoposide and bleomycin (BEP), followed by radiotherapy on the left iliac and paraortic lymphatic ganglions. The control through computed tomography after chemotherapy and radiotherapy shown regression of the lymphadenomegaly. The patient continues to be rigorously followed, since the sarcomatous component ordinarily has high recurrence rates and poor prognosis

Vantagens na remocao da sonda Foley 24 horas apos resseccao transuretral da prostata

Foi realizada uma analise retrospectiva de 323 pacientes submetidos a Resseccao Transuretral (RTU) de prostata no periodo de janeiro de 1989 a janeiro de 1993, com retirada da sonda Foley no primeiro dia pos operatorio. Comparado com a literatura mundial sobre RTU de prostata, onde a sonda Foley e retirada em um prazo minimo de 3 dias, nao foram notadas diferencas entre as complicacoes, sintomatologia e recuperacao pos operatoria dos pacientes. Alem disso foi possivel reduzir os dias de internacao para 2,5 com consequente reducao dos gastos hospitalares em aproximadamente 30 por cento. Conclui-se com este estudo que a remocao da sonda Foley no primeiro dia de pos operatorio e um procedimento seguro diminuindo a morbidade destes pacientes como tambem os custos hospitalares se comparado a retirada da sonda no terceiro dia pos RTU.
