Can we predict which patients will experience resolution of detrusor overactivity after transurethral resection of the prostate?

PURPOSE: We determined which clinical and urodynamic variables may be related to persistent detrusor overactivity after transurethral resection of the prostate. MATERIALS AND METHODS: We studied 46 patients with bladder outlet obstruction due to benign prostatic hyperplasia who were treated with transurethral prostate resection from 2011 to 2012. All patients underwent urodynamic analysis preoperatively and 12 months postoperatively. Clinical and urodynamic variables in the preoperative period were correlated with the resolution of detrusor overactivity postoperatively. RESULTS: Patients with detrusor overactivity in the preoperative period were older (65.2 vs 61.1 years, p = 0.041) and had a higher I-PSS (International Prostate Symptom Score) (25.2 vs 19, p = 0.014) and higher maximum flow rate (8.6 vs 6.6 ml per second, p = 0.039). Patients with persistent detrusor overactivity were statistically older than those with resolution (69 vs 63 years, p = 0.043). Detrusor overactivity persisted in 63.6% of patients with maximum cystometric capacity less than 250 ml compared to 20% of those with greater than 250 ml (p = 0.024). When analyzing urodynamic variables together, we found a 66.7% chance of persistent detrusor overactivity in patients with maximum cystometric capacity less than 250 ml and detrusor overactivity amplitude greater than 40 cm H2O (p = 0.041). When these characteristics were associated with early detrusor overactivity, the chance of persistent detrusor overactivity was 83.3% (p = 0.013). CONCLUSIONS: Advanced patient age together with low maximum cystometric capacity, and early and high detrusor overactivity amplitude are the most important predictors of persistent detrusor overactivity after relief of bladder outlet obstruction.

Renal artery pseudoaneurysm after blunt renal trauma: report on three cases and review of the literature.

CONTEXT: Renal artery pseudoaneurysm is a rare complication after renal injury but should be suspected whenever there is recurrent hematuria after renal trauma. CASE REPORTS: We present three cases of pseudoaneurysm after blunt renal trauma and a review of the literature. All patients underwent renal angiography. Two cases were diagnosed during the initial hospital stay due to hematuria, or in the follow-up period during recovery. One patient was hemodynamically unstable. Two patients successfully underwent coil embolization in a single session. In the other case, selective embolization was attempted, but was unsuccessful because artery catheterization was impossible. Procedural and medical success and complications were retrospectively assessed from the patients' records. The clinical presentation, treatment options and clinical decisions are discussed. CONCLUSIONS: Renal artery pseudoaneurysm may develop acutely or even years after the initial injury. Signs and symptoms may have a wide spectrum of presentation. Selective angiographic embolization is an effective treatment that reduces the extent of parenchymal infarction.

Development and internal validation of an adrenal cortical carcinoma prognostic score for predicting the risk of metastasis and local recurrence.

OBJECTIVE: To develop and internally validate a prognostic score to predict the risk of metastases or recurrence in patients with adrenal cortical carcinomas (ACC). DESIGN: Clinical, laboratory and pathological data from 129 ACC patients, treated in a tertiary centre, were retrospectively reviewed. RESULTS: Using a multivariate binary logistic regression analysis, we developed a prognostic score with five covariates: a functional pattern other than isolated hyperandrogenism, a tumour size >7·5 cm, a primary tumour classified as T3/T4, the presence of microscopic venous invasion and a mitotic index >5/50 high-power fields. The prognostic score was calibrated according to the Hosmer-Lemeshow goodness-of-fit test (P = 0·9329) and exhibited excellent overall performance (Brier score = 0·0738). Finally, the discriminatory ability of the model, determined by the area under the ROC curve (AROC ), was near perfect (AROC , 0·9611; 95% CI, 0·92676-0·99552). The prediction model was internally validated with 200 bootstrap resamples and achieved excellent performance for estimating the risk of metastasis and recurrence in eight additional patients with apparently localized disease at diagnosis. CONCLUSION: We developed and internally validated a prognostic score based on the clinicopathological data that are readily available to any attending physician. Our model can be used to accurately estimate the risk of unfavourable outcomes in ACC patients. This score could be beneficial for both patient counselling and the identification of patients in whom adjuvant mitotane is justified.

CONTEXTO: Pseudoaneurisma de artéria renal é uma complicação rara após lesão renal, mas deve ser suspeitada quando houver hematúria recorrente após trauma renal. RELATO DE CASOS: Três casos de pseudoaneurisma após trauma renal fechado são apresentados, além de revisão da literatura. Todos os pacientes foram submetidos a angiografia renal. Dois dos casos foram diagnosticados durante a estadia hospitalar inicial, por hematúria ou no período de acompanhamento durante a recuperação. Um paciente estava hemodinamicamente instável. Dois pacientes foram submetidos a embolização com coil com sucesso em uma única sessão. No outro caso, a embolização seletiva foi tentada sem sucesso, devido à impossibilidade de cateterização da artéria. O sucesso médico e do procedimento e as complicações foram retrospectivamente avaliados a partir dos registros dos pacientes. A apresentação clínica, opções de tratamento e decisões clínicas são discutidas. CONCLUSÕES: Pseudoaneurisma de artéria renal pode se desenvolver agudamente ou até mesmo anos após o trauma inicial. Sinais e sintomas podem ter um amplo espectro de apresentação. Embolização angiográfica seletiva é um tratamento efetivo, reduzindo a extensão de infarto parenquimatoso. .

Sclerotherapy of hydroceles and spermatoceles with alcohol: results and effects on the semen analysis.

PURPOSE: To evaluate the success rates of sclerotherapy of the tunica vaginalis with alcohol for the treatment of hydroceles and/or spermatoceles, as well as, evaluation of pain, formation of hematomas, infection and its effects in spermatogenesis. MATERIALS AND METHODS: A total of 69 patients, with offsprings and diagnosis of hydrocele and/or spermatocele, were treated during the period from April 2003 to June 2007. Semen analysis was obtained from patients who were able to provide us with samples. The sclerotherapy with alcohol at 99.5% was undertaken as outpatient procedure. RESULTS: The average volume drained pre-sclerotherapy was 279.82 mL (27 to 1145). The median follow-up was 43 months (9 to 80). A total of 114 procedures were performed on 84 units, with an average of 1.35 procedures/unit and an overall success rate of 97.62%. Of the 69 patients, 7 (10.14%) reported minor pain immediately after the procedure, 3 (4.35%) moderate pain and 2 (2.89%) intense pain. Post-Sclerotherapy spermograms revealed reduction of the parameters regarding: concentration, motility and morphology up to 6 months post procedure, with return to normal parameters 12th months after procedure. CONCLUSIONS: Sclerotherapy of hydroceles and spermatoceles with 99.5% alcohol is an efficient procedure that can be performed without difficulties, cost-effectiveness, with few side effects and which may be performed in patients who wish fertility.

Urological complication following aortoiliac graft: case report and review of the literature.

CONTEXT: Ureteral stenosis and ureterohydronephrosis may be serious complications of aortoiliac or aortofemoral reconstructive surgery. CASE REPORT: A 62-year-old female patient presented with a six-month history of left lumbar pain. She was a smoker, and had mild chronic arterial hypertension and Takayasu arteritis. She had previously undergone three vascular interventions. In two procedures, Dacron prostheses were necessary. Excretory urography showed moderate left ureterohydronephrosis and revealed a filling defect in the ureter close to where the iliac vessels cross. This finding was compatible with ureteral stenosis, and the aortoiliac graft may have been the reason for this inflammatory process. The patient underwent laparotomy, which showed that there was a relationship between the ureteral stenosis and the vascular prosthesis. Segmental ureterectomy and end-to-end ureteroplasty with the ureter crossing over the prosthesis anteriorly were performed. There were no complications. The early and late postoperative periods were uneventful. The patient evolved well and the results from a new excretory urogram were normal. We concluded that symptomatic ureterohydronephrosis following aortoiliac graft is a real complication and needs to be quickly diagnosed and treated by urologists.

INTRODUÇÃO: Estenose ureteral e ureterohidronefrose podem ser sérias complicações da cirurgia reconstrutiva aorto-femoral ou aorto-ilíaca. RELATO DE CASO: Uma paciente de 62 anos apresentou-se referindo história de dor lombar a esquerda há seis meses. Ela era fumante, portadora de hipertensão arterial crônica leve e arterite de Takayasu. Havia sido submetida a três intervenções vasculares. Em dois procedimentos o uso de prótese de Dacron foi necessário. Uma urografia excretora revelou moderada ureterohidronefrose à esquerda e falha de enchimento no ureter próximo ao cruzamento dos vasos ilíacos. Esse achado era compatível com uma estenose ureteral e o enxerto aorto-ilíaco poderia ser a causa do processo inflamatório. A paciente foi submetida a laparotomia, que evidenciou a relação entre estenose ureteral e a prótese vascular. Ureterectomia segmentar e uretroplastia término-terminal com o ureter passando anteriormente à prótese foram realizadas. Não ocorreram complicações. Os períodos de pós-operatório precoce e tardio transcorreram sem intercorrências. A paciente evoluiu bem e uma nova urografia excretora apresenta-se normal. Concluímos que ureterohidronefrose sintomática após enxerto aorto-ilíaco é uma complicação real e precisa ser rapidamente diagnosticada e tratada pelo urologista.

Three cases of hypertension and renal arteriovenous fistula with a de novo fistula.

The Renal Arteriovenous Fistula (RAVF) is a rare and potentially reversible cause of hypertension and kidney and/or heart failure. The treatment of RAVF aims at preserving the most of the renal parenchyma and, concomitantly, eradicating the symptoms and hemodynamic effects caused by the RAVF. The present study reports three cases of RAVF, including one case of a de novo idiopathic RAVF, which presented with hypertension and kidney and/or heart failure and describes the therapeutic measures used to treat these patients as well as the outcomes.

Analysis of glucose-dependent insulinotropic peptide receptor (GIPR) and luteinizing hormone receptor (LHCGR) expression in human adrenocortical hyperplasia.

OBJECTIVE: To analyze the aberrant expression of the GIPR and LHCGR in different forms of adrenocortical hyperplasia: ACTH-independent macronodular adrenal hyperplasia (AIMAH), primary pigmented nodular adrenocortical disease (PPNAD) and diffuse adrenal hyperplasia secondary to Cushing's disease (DAHCD). METHODS: We quantified GIPR and LHCGR expressions using real time PCR in 20 patients with adrenocortical hyperplasia (seven with AIMAH, five with PPNAD, and eight with DAHCD). Normal adrenals tissues were used as control and the relative expression was compared with beta-actin. RESULTS: GIPR and LHCGR expressions were demonstrated in all tissues studied. Median GIPR and LHCGR mRNA levels were 1.6; 0.4; 0.5 and 1.3; 0.9; 1.0 in adrenocortical tissues from AIMAH, PPNAD and DAHCD respectively. There were no differences between GIPR and LHCGR expressions in all tissues studied. CONCLUSIONS: GIPR and LHCGR overexpression were not identified in the studied cases, thus suggesting that this molecular mechanism is not involved in adrenocortical hyperplasia in our patients.

Microsurgical testicular denervation for the treatment of chronic testicular pain initial results.

INTRODUCTION: Chronic testicular pain remains an important challenge for urologists. Currently, the treatment plan is primarily empirical, with the first approach consisting of clinical measures. However, some patients remain in pain despite a conservative treatment protocol and, for them, it is possible to perform a surgical procedure that involves severing the scrotal and spermatic branches of the genitofemoral and ilioinguinal nerve fibers. METHODS: In our institution, 60 patients were evaluated and treated for idiopathic chronic testicular pain between January 2003 and July 2007. Priority was give to clinical treatment, which evolved from simple to more complex measures. Microsurgical treatment was performed on those who experienced no considerable pain relief (10 individuals in our study). RESULTS: Over a twenty-four-month follow-up period, 70% of patients showed complete remission and 20% exhibited partial relief from pain.

OBJETIVO: Analisar a expressão aberrante do GIPR e do LHCGR em diferentes formas de hiperplasias adrenocorticais: hiperplasia adrenal macronodular independente de ACTH (AIMAH), doença adrenocortical nodular pigmentada primária (PPNAD) e hiperplasia adrenal difusa secundária à doença de Cushing (DAHCD). MÉTODOS: Quantificou-se por PCR em tempo real a expressão desses receptores em 20 pacientes: sete com AIMAH, cinco com PPNAD e oito com DAHCD. Adrenais normais foram utilizadas como controle e a expressão relativa desses receptores foi comparada à expressão da β-actina. RESULTADOS: A expressão desses receptores foi demonstrada em todos os tecidos estudados. A mediana da expressão do GIPR e do LHCGR foi de 1,6; 0,4; 0,5 e de 1,3; 0,9; 1,0 nos tecidos dos pacientes com AIMAH, PPNAD e DAHCD, respectivamente. Não houve diferença significativa na expressão desses receptores nos tecidos estudados. CONCLUSÕES: Hiperexpressão do GIPR e do LHCGR não foi observada, sugerindo que esse mecanismo não está envolvido na patogênese molecular da hiperplasia adrenal nesses pacientes.

Preliminary findings from a new animal model for Peyronie's disease involving extracorporeal shock waves.

OBJECTIVE: To develop an experimental model in rabbits to analyse the efficiency of extracorporeal shock wave therapy (ESWT) for Peyronie's disease. MATERIALS AND METHODS: We used 15 adult male rabbits divided into three equal groups. In group 1 (no penile ESWT) rabbits had three sessions of ESWT with 2000 shocks each (15 kV), but a rubber mat was placed between the shock head and rabbit to protect the penis; the rabbits were killed at 7 days after the last session of ESWT. In group 2 the rabbits had three sessions of ESWT using the same parameters, and were killed immediately after the last session to analyse the penis. In group 3 the rabbits had three sessions of ESWT as before but were killed at 7 days after the last session, and the penile tissue analysed macroscopically and histologically. RESULTS: The results showed clearly that the model was efficient, creating a similar situation to that when applying ESWT in the human penis. All of the rabbits in groups 2 and 3 had haematomas and diffuse petechiae after ESWT, and only four had urethral and penile bleeding. Almost all macroscopic changes disappeared after 48 h and only one rabbit in group 3 after 7 days had a haematoma on the dorsal penile surface. The histology (assessed using haematoxylin and eosin staining) of the cavernous body of the penis showed: unchanged histology in group 1; in group 2 there was a dilated and congested vascular space in the cavernous body, with interstitial extensive bleeding in the dermis; and in group 3 there was an increase in interstitial fibrous tissue in the cavernous septum, with deposition of collagen fibres and thickening of the tunica albuginea. CONCLUSION: The present model was efficient in producing tissue injury in the normal penis when treated with ESWT, suggesting that this promising model should be considered for use future studies of Peyronie's disease.

Expression profiles of the glucose-dependent insulinotropic peptide receptor and LHCGR in sporadic adrenocortical tumors.

Glucose-dependent insulinotropic peptide receptor (GIPR) and LHCGR are G-protein-coupled receptors with a wide tissue expression pattern. Aberrant expression of these receptors has rarely been demonstrated in adult sporadic adrenocortical tumors with a lack of data on pediatric tumors. We quantified the GIPR and LHCGR expression in a large cohort of 55 patients (25 children and 30 adults) with functioning and non-functioning sporadic adrenocortical tumors. Thirty-eight tumors were classified as adenomas whereas 17 were carcinomas. GIPR and LHCGR expression were analyzed by real-time PCR and normal human pancreatic and testicular tissue samples were used as positive controls. Mean expression values were determined by fold increase in comparison with a normal adrenal pool. GIPR mRNA levels were significantly higher in adrenocortical carcinomas than in adenomas from both pediatric and adult groups. LHCGR expression was similar in both carcinomas and adenomas from the pediatric group but significantly lower in carcinomas than in adenomas from the adult group (median 0.06 and 2.3 respectively, P<0.001). GIPR was detected by immunohistochemistry in both pediatric and adult tumors. Staining and real-time PCR results correlated positively only when GIPR mRNA levels were increased at least two-fold in comparison with normal adrenal expression levels. In conclusion, GIPR overexpression was observed in pediatric and adult adrenocortical tumors and very low levels of LHCGR expression were found in all adult adrenocortical carcinomas.

Urogenital tuberculosis in immunocompromised patients.

OBJECTIVE: Compare the clinicoradiological presentation of urogenital tuberculosis (UGT) between immunocompromised and nonimmunocompromised patients. PATIENTS AND METHODS: Eighty patients diagnosed with UGT were divided into two groups: eight immunocompromised patients (four with acquired immunodeficiency syndrome [AIDS], and four renal transplant patients on immunosuppressive therapy) and 72 nonimmunocompromised patients. The groups were compared as for age, signs and symptoms, diagnostic approach, pattern of urogenital organ involvement, and early specific mortality (within 6 months from diagnosis). RESULTS: AIDS patients were younger (median age 26 years, range 16-38 years), and renal transplant patients were older (median age 51.5 years, range 45-57 years), compared with the nonimmunocompromised subjects (median age 35 years, range 12-75 years). Immunocompromised patients had greater frequency of fever (87.5% versus 43.1%, P = 0.024), lower frequency of storage symptoms (37.5% versus 76.4%, P = 0.033), shorter length of disease (<6 months: 87.5% versus 2.8%, P < 0.001), and larger frequency of disseminated tuberculosis (62.5% versus 18.1%, P = 0.012). Predominantly parenchymatous renal involvement was more frequent in immunocompromised patients (87.5% versus 6.2%, P < 0.001), who also had lower frequency of stenosis of the collecting system (12.5% versus 93.8%, P < 0.001) and contracted bladder (12.5% versus 65.3%, P = 0.001). CONCLUSIONS: UGT has a different clinicoradiological presentation in immunocompromised patients, with predominance of systemic symptoms, disseminated tuberculosis, multiple parenchymatous renal foci, and lower frequency of lesions of the collecting system. In the context of immunosuppression, UGT behaves as a severe bacterial infection, with bacteremia and visceral metastatic foci.

Bladder involvement in systemic lupus erythematosus / Envolvimento vesical no lúpus eritematoso sistêmico

Objective: To study bladder involvement in systemic lupus erythematosus patients through clinical and laboratorial evaluation, ultrasonography, radiological and endoscopic examination. Methods: Thirty-nine patients, either outpatients or inpatients at the Department of Rheumatology of Hospital das Clínicas da Faculdade de Medicina from Universidade de São Paulo were evaluated as to clinical and laboratorial data. All patients were submitted to ultrasonographic evaluation of the upper urinary tract, radiological and endoscopic examinations of the middle and lower urinary tracts. Results: Mean age of patients varied between 13 and 62 years (median = 29 years). Thirty-six were females and three were males. The disease varied from 6 months to 22 years (median three years and one month). Clinical and laboratory activity of the disease was present in 30 patients. Twenty-two patients had the diagnosis of lupus established for three years or more. Twenty-five patients were asymptomatic and all had received corticosteroids for treatment at least once. Twenty-three received antimalarial drugs; ten received cytostatics, and seven patients received non-steroid anti-inflammatory drugs. Upper urinary tract ultrasonography was normal in all cases but one with staghorn calculus associated with neurogenic bladder secondary to neurological involvement by the disease. Vesicoureteral reflux was observed in two cases. Other two patients had significant post-voiding residual urine, both with neurogenic bladder secondary to nervous system involvement by lupus. The average bladder maximum capacity in an awaken patient was 342 mL, and was decreased in 18.9% of cases. This subgroup of patients presented a greater frequency of urinary symptoms and greater use of cytostatic drugs (Z > Z5%). A pathognomonic cystoscopic pattern of bladder involvement in systemic lupus erythematosus could not be established. Cystoscopic aspects similar to those seen in the initial or minor forms of interstitial cystitis were present in 43.2% of patients. This finding was more frequent when cytostatic drugs were used for treating the disease. Conclusions: There was bladder involvement in systemic lupus erythematosus, even in asymptomatic patients, demonstrated by the occurrence of cystoscopic abnormalities or by reduced bladder maximum capacity associated with the presence of suprapubic pain, urinary irritation symptoms and the use of cytostatic drugs.

Objetivo: Estudar o envolvimento vesical em pacientes com lúpus eritematoso sistêmico (LES) por meio de avaliações clínica, laboratorial, ultrassonográfica e de estudos radiológico e endoscópico. Métodos: Trinta e nove pacientes ambulatoriais ou internados no Serviço de Reumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo foram avaliados clínica e laboratorialmente. Todos foram submetidos à avaliação do trato urinário superior por meio da ultrassonografia, e a exames radiológicos e endoscópicos para a avaliação dos tratos médio e inferior. Resultados: A idade dos pacientes variou de 13 a 62 anos (mediana = 29 anos). Trinta e seis pacientes eram do sexo feminino e três do sexo masculino. O tempo de doença variou de seis meses a 22 anos (mediana = três anos e um mês). Trinta pacientes apresentavam atividade da doença na ocasião do estudo. O diagnóstico de lúpus havia sido estabelecido havia três anos ou mais em 22 pacientes. Vinte e cinco pacientes eram assintomáticos em relação às queixas urinárias e todos haviam feito uso de corticoides em alguma fase do tratamento. Vinte e três receberam antimaláricos; dez, citostáticos e sete anti-inflamatórios não-hormonais. A ultrassonografia do trato urinário superior foi normal em todos os casos, exceto um que apresentou cálculo coraliforme associado à bexiga neurogênica devido a envolvimento neurológico pelo lúpus. Refluxo vésico-ureteral foi demonstrado em dois pacientes e, em outros dois casos, observava-se grande resíduo pós-miccional secundário à lesão neurológica pela doença de base. A média da capacidade vesical máxima com paciente desperto foi de 342 ml e, em 18,9% dos casos este parâmetro estava diminuído. Este subgrupo apresentou maior incidência de manifestações urinárias e maior frequência de emprego de citostáticos (Z > Z5%). Não se caracterizou padrão diacrítico de participação vesical na doença. Em 43,2% dos pacientes, detectaram-se aspectos cistoscópicos semelhantes aos descritos para a forma precoce ou menor de cistite intersticial, guardando dependência apenas com o emprego de citostáticos no tratamento do lúpus eritematoso sistêmico. Conclusões: Demonstrou-se o envolvimento vesical no lúpus eritematoso sistêmico, mesmo em pacientes assintomáticos e que se manifestou pela ocorrência de alterações cistoscópicas e pela diminuição da capacidade vesical máxima em paciente desperto, estando esta associada à presença de dor suprapúbica à repleção vesical e manifestações irritativas urinárias, bem como ao uso de citostáticos.
