Rate of spontaneous voiding recovery after acute urinary retention due to bed rest in the hospital setting in a nonurological population clinical study of the relationship between lower limbs and bladder function.

OBJECTIVES: To understand the clinical relationship between lower limbs functions and the recovery of spontaneous voiding after an acute urinary retention (AUR) in older patients admitted to hospitals for non-urological causes using clinical parameters. MATERIALS AND METHODS: 56 adult patients (32 men; mean age: 77.9 ± 8.3 and 24 women; mean age 82.1 ± 4.6) with AUR were prospectively followed with validated Physical Performance Mobility Exam (PPME) instrument to evaluate the relationship between the recovery of mobility capacity and spontaneous voiding. After a short period of permanent bladder drainage patients started CIC along evaluation by PPME during hospitalization and at 7, 15, 30 60, 90, and 180 days of discharge. Mann-Whitney U, chi-square test and ANOVA tests were used. RESULTS: All patients were hospitalized for at least 15 days (Median 26.3 ± 4.1 days). Progressive improvement on mobility scale measured by PPME was observed after leaving ICU and along the initial 7 days of hospitalization but with a deterioration if hospitalization extends beyond 15 days (p<0.03). Prolonged hospital stay impairs mobility in all domains (p<0.05) except step-up and transfer skills (p<0.02) although a recovery rate on spontaneous voiding persistented. Restoration of spontaneous voiding was accompanied by improvement on mobility scale (p<0.02). Recovery of spontaneous voiding was markedly observed after discharging the hospital. All patients recovered spontaneous voiding until 6 months of follow-up. CONCLUSIONS: Recovery to spontaneous voiding after acute urinary retention in the hospital setting may be anticipated by evaluation of lower limbs function measured by validated instruments.

Can We State Stable Bladder? How Many Repetitions Should We Do for an Appropriate Demonstration of Involuntary Detrusor Contraction?

AIMS: Involuntary Detrusor Contraction (IDC) may alter therapeutic plans; therefore, urodynamic demonstration (UD) is pivotal. We explore if same session repetitions enhance its demonstration and minimize false-negative results. METHODS: Two hundred fifty two women (mean age 47 ± 5.7) had 4 full repetitions of UD with the last round filled with 4°C fluid (Ice-water test). IDC was diagnosed if with at least 3 cm H2O after artifacts were ruled out. RESULTS: 44.4% of the cases showed IDC in the first round of the exam but it could be demonstrated in 88.5% of the women if 4 rounds are taken into account. Only 2 cases showed IDC exclusively in the first round. Nine cases (3.5%) showed IDC in the first round and only on Ice-test, while all other IDC-detected cases revealed it in scattered patterns along the repetitions. Likewise, IDC detection on the second, third and fourth rounds varied widely and unpredictably, many failing to show a consistent pattern of presentation after its detection. IDC wave amplitude did not show any correlation to the detection. CONCLUSIONS: Urodynamic repetition is a necessary procedure where IDC is important to demonstrate, as its false-negative rate is high and its unpredictable pattern of detection may be improved by repetition.

Involuntary detrusor contraction is a frequent finding in patients with recurrent urinary tract infections.

OBJECTIVE: To check whether subtle voiding dysfunction is related to recurrent urinary tract infection (rUTI). METHODS: 254 consecutive patients with at least four episodes of urinary tract infection (UTI) were studied. At least three repeat urodynamic evaluations with an additional ice water test to maximize the detection of involuntary detrusor contraction (IDC) were used. Stress urinary incontinence cases were used as controls. Nonparametric univariate and multivariate analyses were used for statistics. RESULTS: IDC was detected in 83.6% of patients in the rUTI group and in 31.7% in the control group. IDC was <15 cm H2O in 54.7% whereas high-amplitude (>50 cm H2O) IDC was observed in 6.8% in the rUTI group. Female urinary tract obstruction was diagnosed in 16.8% of patients in the rUTI group and in 7.9% in the control group. Residual volume, PdetQmax and Qmax were not predictive of UTI recurrence. Symptoms were similar in both groups. CONCLUSIONS: Patients with rUTI present with covert bladder dysfunctions represented by detrusor overactivity.

Urodynamic after-contraction waves: a large observational study in an adult female population and correlation with bladder and ureter emptying functions in women.

OBJECTIVE: To evaluate different patterns of after-contraction (A-C) waves detected during urodynamic evaluation in women. PATIENTS AND METHODS: 4,110 women were prospectively observed regarding the presence of A-C waves upon urodynamic evaluation. Intravenous pyelography and ultrasound were requested. Paired t test, χ(2) test, Wilcoxon's rank sum test and correlation analysis were performed with a 95% significance level. RESULTS: There were three distinguishing patterns of A-C: type I - detrusor contraction after the regular voiding phase, type II - detrusor contraction persisting after the flow rate had stopped, and type III - rebound of the detrusor contraction after the flow. A-C was observed in 13.9% of the women. Type I A-C wave patterns were present in 68 patients (11.8%), type II A-C wave patterns in 477 patients (83.2%), and type III A-C wave patterns in 28 patients (10.3%). Studies with intravenous pyelography and ultrasound very frequently showed bladder mucosa, muscle thickening or trabeculation. Secondary ureterectasis related to A-C waves was also observed. Additionally, watts factor, maximum flow rate, detrusor pressure and opening detrusor pressure were markedly elevated in patients with type III A-C, suggesting enhanced detrusor contraction in these A-C waves. CONCLUSION: A-C waves are a real urodynamic entity with different patterns of presentation and with clinical and morphological alterations.

One hundred cases of SUI treatment that failed: a prospective observational study on the behavior of patients after surgical failure.

OBJECTIVES: Determine what happens to patients after unsuccessful SUI operations and to explore the reasons why these patients change doctors. MATERIALS AND METHODS: One hundred consecutive failed patients treated for SUI were interviewed about the exams requested after persistence of the incontinence as well as the reasons they abandoned their primary doctors through a structured questionnaire. RESULTS: Among the patients with cases of anterior colporrhaphy, bladder suspensions or slings, 34.3%, 13.7% and 8.3%, respectively, were not offered any further type of investigative procedures to clarify the failure. Urodynamic evaluations were recommended in 75% of failed slings, and 66.6% of the patients proceeded with these tests. In contrast, only 31% of patients with bladder suspensions and 40% of patients with anterior colporrhaphy were recommended for urodynamic investigations, and only 44.4% and 28.5% of them, respectively, proceeded with the option. Patients' delusions were reinforced by the doctors' attitude toward the investigations. Vacuous justifications and the lack of intention to seek improvement were the driving forces causing the patients to change doctors. CONCLUSION: Unsuccessful patients are evaluated in a non-protocol form. Difficulty in clarifying the reasons for surgical failure and the disruption of the doctor-patient relationship are the main reasons why patients abandon them.

"Non-metastatic, Castration-resistant Prostate Cancer: Diagnostic and Treatment Recommendations by an Expert Panel from Brazil".

INTRODUCTION: Non-metastatic, castration-resistant prostate cancer (nmCRPC) is an important clinical stage of prostate cancer, prior to morbidity and mortality from clinical metastases. In particular, the introduction of novel androgen-receptor signaling inhibitors (ARSi) has changed the therapeutic landscape in nmCRPC. Given recent developments in this field, we update our recommendations for the management of nmCRPC. METHODS: A panel of 51 invited medical oncologists and urologists convened in May of 2021 with the aim of discussing and providing recommendations regarding the most relevant issues concerning staging methods, antineoplastic therapy, osteoclast-targeted therapy, and patient follow-up in nmCRPC. Panel members considered the available evidence and their practical experience to address the 73 multiple-choice questions presented. RESULTS: Key recommendations and findings include the reliance on prostate-specific antigen doubling time for treatment decisions, the absence of a clear preference between conventional and novel (i.e., positron-emission tomography-based) imaging techniques, the increasing role of ARSis in various settings, the general view that ARSis have similar efficacy. Panelists highlighted the slight preference for darolutamide, when safety is of greater concern, and a continued need to develop high-level evidence to guide the intensity of follow-up in this subset of prostate cancer. DISCUSSION: Despite the limitations associated with a consensus panel, the topics addressed are relevant in current practice, and the recommendations can help practicing clinicians to provide state-of-the-art treatment to patients with nmCRPC in Brazil and other countries with similar healthcare settings.

Wünderlich Syndrome in Renal Transplant Recipients: A Case Report and Literature Review.

BACKGROUND: Wünderlich syndrome, or spontaneous atraumatic renal hemorrhage, is a clinical entity rarely described in the native kidney of patients who have undergone renal transplant. Although its manifestation is quite similar in reported cases, it may present few symptoms, from bleeding of unidentified etiology to dramatic pictures associated with hypovolemic shock. There are few reports of spontaneous hemorrhage of a native kidney after kidney transplantation. CASE REPORT: We present a 38-year-old male patient who developed hemorrhage of a ruptured native kidney after a late renal transplantation. We analyze what has been reported in the literature and highlight the possibility of this complication after kidney transplantation. Imaging exams and surgical specimen demonstrated the presence of ruptured angiomyolipoma in the patient's native right kidney. The postoperative period was not complicated, with a benign clinical evolution. CONCLUSION: Although rare in patients who have undergone renal transplant, it is justified to suggest Wünderlich syndrome in the presence of acute flank pain, abdominal tenderness, and signs of internal bleeding (Lenk's triad), with unexplained hemoglobin drop.

A randomized and prospective study on the value of antibiotic prophylaxis administration in transurethral resection of the prostate.

CONTEXT: Antibiotic prophylaxis in transurethral resection of the prostate is a regular practice in urology. However, its prophylactic effect can be questioned when the antiseptic surgical technique is used. Nonetheless, urine culture-oriented antibiotic therapy is the gold standard for avoiding improper medication usage and bacterial resistance. OBJECTIVE: To study the efficacy of antibiotic usage in patients with negative urine cultures, who were submitted to transurethral resection of the prostate. TYPE OF STUDY: Prospective open labeled study. SETTING: Tertiary care referral hospital. PARTICIPANTS: 124 consecutive patients, who were randomly divided into two groups to receive antibiotic prophylaxis or not. MAIN MEASUREMENTS: Cultures from meatus, urine, irrigation and antiseptic fluid, and prostate tissue chips, were compared and analyzed for bacterial sensitivity to the antibiotic used, according to the surgeon's personal criteria. McLennan's test was used for statistical analysis. RESULTS: No statistically significant difference regarding clinical evolution was found between the groups that received or antibiotics or not. Statistical significance was found regarding the occurrence of positive urine cultures during the postoperative period for those not receiving antibiotics, but not in relation to fever, prostate chip culture or bacteremic episodes. Sixty-eight subjects (57.1%) presented positive prostatic tissue culture. There was no specific correlation between the recovered bacteria from the meatus, prostatic tissue chip and urine and the spectrum of the administered antibiotic. Six cases showed the same bacteria in the urine and prostatic tissue chip. Only fifteen cases (25%) in the antibiotic group showed the desired sensitivity directed to the collected bacteria. CONCLUSIONS: Antibiotic prophylaxis for patients whose urine is sterile is debatable in patients who are candidates for transurethral resection of the prostate. Most of the time, the antibiotic agent used is not specific for any of the bacteria recovered from the various sources analyzed.

Impact of Urodynamic Learning on the Management of Benign Prostatic Hyperplasia Issue on Young and Senior Urologists and Reasons to Attend a Voiding Dysfunction Course.

OBJECTIVES: The aims of this study were to compare the impact of urodynamic training on the young urologists after fellowship training as well as on senior urologists who attend regular courses on the management of benign prostatic hyperplasia (BPH) and their capacity to do and interpret urodynamic studies. METHODS: Sixty-four consecutive young urologists admitted to fellowship program on voiding dysfunctions and 110 senior urologists attending to periodical meetings were interviewed before and after the 3-day-courses regarding their ability to set, interpret and do urodynamic studies. They were also questioned on the reasons that led them to attend the courses and how they use the new concepts to manage BPH. A rank of the used parameters to indicate transurethral resection of the prostate (TURP) in BPH patients were scored before and after the course. RESULTS: Fellowship and senior urologists mainly attended the course because of lack of confidence and belief that this urological issue is too important to be disregarded. A significant portion of both groups do not trust third-party examiners. More than 90% of the urologists acquired confidence in interpreting, setting and were able to do the exam after the course. The majority of both groups believed urodynamic study was essential to manage BPH, disregarding volume as the main reason to operate on patients. Many outdated parameters became less important on the decision to operate. CONCLUSIONS: Doctors exposed to intensive or long urodynamic training dramatically changed their perceptions on the utility of this tool and became more attentive it.

Slings may not fail as frequently as believed for stress urinary incontinence: the misinterpretation of postoperative voiding dysfunction as failure based on patient report.

OBJECTIVE: : Sling operations may obstruct the urethra, promoting voiding dysfunction and secondary urine leakage that are incorrectly attributed to surgical failure. METHODS: : We prospectively evaluated the evolution of urinary symptoms in the postoperative follow-up of 108 polypropylene sling cases. Patients presented for follow-up at 1, 3, 6, 12, 18, 24, 36, and 48 months for review of individual urinary symptoms. Statistical analysis used Fisher exact test. RESULTS: : On the 30th postoperative day, 100% of the cases were cured of stress urinary incontinence, although frequency (62.9%), urgency (29.6%), urge-incontinence (23.1%), nocturia (28.6%), incomplete voiding sensation (11.1%), and poor stream (11.1%) persisted. At 3 months, 16.6% reported frequency, 38% complained of urgency, and 29.6% were troubled by nocturia. True urinary leakage under stress was resolved in 100% of cases by the first visit and did not show any further decrease when specifically questioned. Pad usage decreased after 3 months but did not completely disappear after 48 months. A total of 94.4% of the cases achieved total continence and clinical satisfaction after 4 years of follow-up, in parallel with the steady disappearance of voiding dysfunction observed in the early postoperative period. CONCLUSIONS: : Voiding dysfunction after sling procedures is frequent but transitory. As symptoms improve or disappear, patients tend to miss their follow-up. In this study, 94.4% of the cases had complete dryness and satisfaction with the operation.

Pubo-fascial versus vaginal sling operation for the treatment of stress urinary incontinence: a prospective study.

AIMS: To compare the long-term results of stress urinary incontinence (SUI) treatment involving the fascial or vaginal sling operations. MATERIAL AND METHODS: Two-hundred-thirty-two women were consecutively submitted to fascial or vaginal sling operations due to urodynamic proven SUI. The fascial group had a median age of 47.3 years with a parity of 2.2 and 1.8 surgeries/patient, while the vaginal group demonstrated a median age of 48.5 years with a median parity of 3.1 and 2.2 anterior surgeries/patient. The results were subjectively classified as cured--no further pads, greatly improved--very rare dribbling, improved--eventual dribbling necessitating one pad, no cure--with no urine loss change and worse. The number of pads/day, the presence of urgency or urge-incontinence episodes were all measured. Statistical analysis using Fisher's exact test was employed. RESULTS: The patients were followed up for an average time of 70.3 and 44.9 months, in the fascial and vaginal sling group respectively. Subjective clinical success rate was 93.7% for the fascial sling group and 79.8% for the vaginal one, however, the stratification of the results favored the fascial sling group mostly with 74.4% (94 cases) of the cases with total urinary control and no voiding dysfunctions. Only two cases (1.6%) in this group classified themselves as worsened. On the other hand, the vaginal sling subset revealed cure with total clinical satisfaction and no urinary complaint in 61.5% (62 females) (P > 0.05). Thirteen cases (12.5%) reported recurrence of the urine loss under stress and these constituted the failure group. The average number of pads diminished from 3.3 (+/- 0.8) to 0.2 (+/- 0.2) and from 3.2 (+/- 0.7) to 0.6 (+/- 0.5) after the surgery, for the fascial and vaginal sling operations respectively. Return to daily activities occurred after 9.3 days (+/- 1.2, max: 33, min: 2) for the fascial slings and 5.3 days (+/- 0.2, max: 17, min: 2) in the vaginal group. Surgical complications were compared between the groups. Time to urethral voiding varied according to expertise, demonstrating a diminishing tendency after the initial 20 cases. Female obstruction was observed in 11.1% of the fascial slings and 8.6% after vaginal approach, but none in the vaginal group required urethrolysis. Looking individually, the FS group migrated to the worse results while the VWS group started to lose the efficiency after 6 months. CONCLUSIONS: Sling operations are a safe and efficacious option to treat SUI, however, the results can vary according to the technique employed. Shorter efficacy and fewer complications are observed in vaginal wall sling operations, while durable results, but with a higher rate of voiding dysfunctions compromising the long-term clinical satisfaction may be observed after excessive urethral suspensions, as in fascial sling suspension.

A randomized and prospective study on the value of antibiotic prophylaxis administration in transurethral resection of the prostate

CONTEXTO: A profilaxia antibiótica nas ressecções transuretrais da próstata é uma prática regular e freqüente na clínica urológica. No entanto, seu efeito profilático e bactericida protetor pode ser contestado se procedimentos assépticos são utilizados na realização da cirurgia, sobretudo em pacientes com urina estéril. No caso de infecção urinária, a identificação dos germes para escolha do antibiótico adequado pode ser necessária. OBJETIVO: Verificar a eficácia da antibioticoprofilaxia em pacientes com urina estéril submetidos a ressecção transuretral de próstata. TIPO DE ESTUDO: Prospectivo num centro de referência de tratamento urológico, aberto. LOCAL: Hospital de referência terciária. PARTICIPANTES: 124 pacientes. VARIÁVEIS ESTUDADAS: 124 pacientes consecutivos foram randomicamente divididos em dois grupos para receber ou não antibioticoterapia profilática na ressecção transuretral de próstata. Cultura do meato uretral, urina, líquido irrigante e anti-séptico, além dos fragmentos de próstata ressecados foram analisados quanto a sensibilidade a antibióticos, escolhidos a critério do cirurgião, e determinada a partir de antibiograma com as cepas bacterianas identificadas nos sítios mencionados. RESULTADOS: Não se encontrou diferença estatisticamente significante na evolução clínica de ambos os grupos. Aqueles que receberam antibioticoprofilaxia apresentaram menor freqüência de cultura urinária positiva do que aqueles que não receberam profilaxia. No entanto, na observação da evolução clínica de ambos os grupos, o uso de antibiótico não mostrou qualquer benefício no que concerne à ocorrência de febre, positividade das culturas obtidas dos fragmentos de próstata ressecados ou episódios de bacteremia. 68 casos (57,1%) apresentaram cultura positiva do tecido prostático. Entretanto, não houve correlação entre a bactéria identificada a partir do tecido prostático e de outros locais, tais como meato, urina, líquido irrigante ou anti-séptico utilizado. Somente em seis casos foi encontrada a mesma bactéria no tecido prostático e na urina pós-operatória. Apenas em 15 casos (25%) do grupo antibiótico observou-se a sensibilidade esperada da bactéria identificada ao antibiótico utilizado...

Lymphocele: a possible relationship with acute cellular rejection in kidney transplantation

CONTEXT: The incidence of lymphocele after renal transplantation varies between 0.6 and 18 percent of cases, and many factors have been associated to its etiology. Cellular rejection of the kidney allograft has been described as a possible causal factor of lymphocele. OBJECTIVE: To analyze the possible relationship between lymphocele and acute cellular rejection. DESIGN: A retrospective study. SETTING: A referral hospital center. SAMPLE: 170 patients submitted to kidney transplantation from March 1992 to January 1997. A standard technique for renal transplantation was used. RESULTS: Of the 19 patients that developed lymphocele, 16 presented at least one episode of acute cell rejection (84 percent), and were treated with methylprednisolone. The relation between lymphocele and rejection was statistically significant (p = 0.04). Treatment of lymphocele consisted of peritoneal marsupialization in 3 patients (15.3 percent), percutaneous drainage in 7 (36.8 percent), laparascopic marsupialization in 2 (10.5 percent), and conservative treatment in 7 patients (36.8percent. Evolution was favorable in 15 patients (78.9 percent), 1 patient (5.3 percent) died due to a cause unrelated to lymphocele, and 3 (15.8 percent) lost the graft due to immunological factors. The average follow-up period was 24.5 months. CONCLUSION: The high incidence of acute cell rejection in patients with lymphocele suggests a possible causal relationship between both conditions

Implantaçäo ureterovesical invaginante no restabelecimento do trato urinário em homotransplante renal: experiência com 250 casos / Ureterovesical implantation with invagination in the repair of the urinary tract in homologous transplantation: experience with 250 cases

Em 250 homotransplantes renais a reconstruçäo do trato urinário foi realizada pela implantaçäo extra vesical com invaginaçäo da anastomose sob musculatura íntegra da bexiga. Nesta operaçäo a anastomose é realizada com fácil apresentaçäo o que permite suturas herméticas e, o posicionamento destas sob um túnel submucoso suturas diminui as possibilidades de deiscências e extravazamento de urina. Os índices de complicaçöes foram consideravelmente baixos: fístulas 1,2%, refluxo 0,8% e estenose 0,4%. Esta técnica, pela facilidade de realizaçäo, e pelos resultados obtidos nos parece ser uma boa alternativa no restabelecimento urinário do transplante renal
