Is there concordance between overactive bladder and detrusor overactivity in men with predominant storage urinary symptoms referred to Functional Urology and Urodynamics Units?

OBJECTIVES: To assess the diagnostic concordance of overactive bladder (OAB) and detrusor overactivity (DO) in male patients with predominant storage lower urinary tract symptoms (LUTS) and evaluate their clinical and urodynamic profile according to DO presence and degree of obstruction. MATERIAL AND METHODS: Epidemiological, cross-sectional multicenter study. A 3-day bladder diary (3dBD), International Prostate Symptom Score (IPSS) and Bladder Control Self-Assessment Questionnaire (B-SAQ) questionnaires were analyzed. Prostate volume was determined by ultrasound. Urodynamic study (UDS) tests were performed. The prevalence of OAB and DO and the degree of clinical concordance (kappa index) were investigated. Descriptive analysis of clinical variables and UDS results was performed, followed by comparisons based on the presence of DO and degree of obstruction. RESULTS: A total of 445 patients were included. The mean age was (SD) 54.8 (9.9) years. According to 3dBD, 89.9% presented increased urinary frequency, 87.9% nocturia, 72.1% urgency, and 31.9% urge urinary incontinence (UUI). Obstruction was present in 36.8%. Concomitant OAB and DO were present in 54.5%. The degree of diagnostic concordance between OAB and DO was low (κ = 0.1772). There were more patients with DO presenting urgency (3dBD and B-SAQ; p < 0.001), UUI (3dBD; p = 0.008) and nocturia (B-SAQ; p < 0.001). Differences were found in terms of prostate volume, IPSS-voiding, maximum flow (Qmax) and post-void residual (p < 0.05) according to the obstruction degree. CONCLUSIONS: Approximately 50% of male patients aged 18-65 years old with predominant storage LUTS, referred to specialized units, have both OAB and DO. Obstruction is present on 1/3. Diagnostic concordance between OAB and DO is poor.

Bladder pain syndrome: Prevalence and routine clinical practice in women attending functional urology and urodynamics units in Spain. / Síndrome de dolor vesical: prevalencia y práctica clínica habitual en mujeres que acuden a Unidades de Urología Funcional y Urodinámica en España.

INTRODUCTION AND OBJECTIVES: Bladder pain syndrome (BPS) is classified as a rare chronic debilitating disease and its diagnosis presents a challenge because its symptoms overlap with those associated with overactive bladder syndrome. The aim of the routine study was to estimate the prevalence of BPS and discover to study the profile of symptoms and clinical practice for patients attending functional urology and urodynamics units. MATERIAL AND METHODS: An epidemiological study in which 37 functional urology and urodynamics units in Spain participated. The prevalence was studied in both sexes. Clinical practice was evaluated for 319 women with BPS (new diagnosis or under review). Clinical and sociodemographic data were collected retrospectively. The results were studied of urine tests, cystoscopy, biopsy, physical examination, bladder diary, and those of the four available questionnaires: Patient Perception of Bladder Condition; Bladder Pain/Interstitial Cystitis Symptom Score; EuroQoL-5 Dimensions-5L and Patient Global Impression of Severity. RESULTS: Five point four percent (503) of the patients who attended these units (9,312) had a diagnosis of BPS (90% [453] females). The tests that were performed most according to the clinical history and anamnesis were: urine test, bladder ultrasound and cystoscopy. The most common symptoms/comorbidities were: pain in the bladder region, increased urinary frequency, nocturia, anxiety and depression. Diagnostic assessment determined pain on hydrodistension (86.9%), positive biopsy (59.2%), myofascial pelvic pain (28.4%), urological phenotype (97.8%), and increased urinary frequency (88.7%). The questionnaires reflected how much the quality of life of these patients was affected. CONCLUSIONS: The prevalence of BPS in functional urology and urodynamics units in Spain is low. No homogeneity was observed in terms of diagnosis between the different participating centres. Therefore, a common methodology is required for the management of patients with BPS in these units, with tools specific to this disorder.

Cognitive function assessment in elderly patients with overactive bladder treated with transdermal oxybutynin. / Evaluación de la función cognitiva en pacientes de edad avanzada con vejiga hiperactiva tratados con oxibutinina transdémica.

INTRODUCTION AND OBJECTIVES: Older patients with overactive bladder under antimuscarinic treatment are especially susceptible to cognitive impairment. The aim was to assess short term changes in cognitive function in elderly patients with overactive bladder treated with transdermal oxybutynin. MATERIALS AND METHODS: Observational, retrospective, multicentre study in patients with overactive bladder aged 65-80 years undergoing treatment with transdermal oxybutynin. Before and after one month of treatment, cognitive function using the Memory Alteration Test and Clock-Drawing Test, changes in symptoms with validated questionnaires, patient perception of treatment response using Treatment Benefit Scale and treatment adherence with the modified Morisky-Green test, were assessed. RESULTS: From 85 eligible patients, 70 completed the assessment (mean age: 71.4±4.5; BMI: 28.7±3.1kg/m2). No cognitive impairment was observed after one month with transdermal oxybutynin: Memory Alteration Test (+1 point; 95%CI: 0.0-1.5), Clock-Drawing Test (0 points; 95%CI: 0.0-0.0). A statistically significant improvement (P<.001) was observed in all urinary storage symptoms, except stress urinary incontinence. There was an improvement in the Bladder Control Self-Assessment Questionnaire (symptom score: -2.27; 95%CI: -2.8, -1.7; P<.001; bother score: -2.73; 95%CI: -3.3, -2.1; P<.001). 70% of patients reported either a stable or improved bladder condition according to the Patient Perception of Bladder Condition questionnaire. 72.8% of patients reported that their urinary problems had improved or greatly improved with an 84.3% treatment adherence. CONCLUSIONS: No cognitive impairment was observed in elderly patients after one month of treatment with transdermal oxybutynin; urinary urgency symptoms improved and there was adequate treatment adherence.

[Urological findings in spinal cord ischemia]. / Manifestaciones urológicas de los accidentes vásculo-medulares.

INTRODUCTION: Spinal cord ischemia is a circulatory disorder of acute or subacute establishment and neurological clinic of medullar section, usually incomplete. We describe clinical and anatomical characteristics, as well as diagnostic methods and therapeuthic used in these patients. MATERIAL AND METHODS: Since 1987 to 2007, 65 patients were diagnosed of spinal cord ischemia in our hospital. Clinical interview, neurological examination and image study were performed. Urodynamic study was performed after medullar shock phase, including cystometry, pressure flow study and external urinary sphincter electromyography. We have reviewed treatment applied in these patients. RESULTS: 65 patients (27 women and 38 men), median age 63 years (15-87). 28 patients (43%) presented high lesion (upper to T7), 32 (49%) middle (T7-L2) and 4 (6%) low lesion (below L2). Flaccid paraplegia and acute urinary retention were the most frequent clinical findings at the begining. Aetiology was determined mainly by Magnetic Resonance. Urodynamic study revealed: 9 patients (47.4%) with high spinal cord lesion and detrusor overactivity (with or without dyssynergia), and 6 (31.5%) with arreflexia; 11 patients (47.8%) with middle spinal cord lesion and detrusor overactivity and 7 patients with arreflexia (30.4%); one patient with low spinal cord lesion and detrusor overactivity, and another one with arreflexia (33%). CONCLUSIONS: There is a good correlation among lesion level and clinical findings in traumatic spinal cord injuries, but this is not the same in spinal cord ischemia. Probably, incomplete and patched lesions in vascular spinal cord injuries could explain this lack of correlation. Therefore, it is mandatory to performe an exhaustive neurological and urological evaluation of these patients in order to select the best treatment and prevent upper urinary tract damage in the future.

[Clinical features and histopathology of prostate cancer diagnosed from the third biopsy]. / Características clínicas e histopatológicas del cáncer de próstata diagnosticado a partir de la tercera biopsia.

OBJECTIVE: To study of histological and clinical features of prostate cancer diagnosed after three or more prostate biopsies in order to assess its clinical relevance and to discard the overdiagnosis of prostate cancer. MATERIAL AND METHODS: We reviewed the clinical records of 61 patients who underwent three or more prostate biopsies between January 2000 and December 2006. The analyzed variables were: age, PSA level, free/total PSA ratio, PSA density, digital rectal examination, prostate volume, sonographic findings and previous malignant lesion strongly associated to the presence of tumor on previous biopsy. We studied the pathology of the tumors diagnosed from the third biopsy, therapeutical approach and its evolution with a minimum follow-up of 3 months. RESULTS: Fifteen out of 61 patients with more than three biopsies had prostate cancer (24,59%) in the third biopsy, 5 out of 14 patients with 4 biopsies (35,71%) and 1 of the 2 cases (50%) who underwent a fifth biopsy. According to the results of biopsy, 6 patients met the criteria of clinically insignificant cancer (28,57%). Curative treatment was performed in all patients: brachytherapy in 5, external beam radiotherapy in 6 and radical prostatectomy in 10. Clinically significant tumors were found in all cases: 2 pT2b tumors and 7 pT2c tumors with negative surgical margins and with an excellent control of the cancer after a minimum follow up of 13 months, and one pT4 tumor with bladder neck infiltration. CONCLUSION: In our practice, overall detection rate of the third, fourth and fifth biopsy is 34,42% corresponding with tumors that could benefit from curative treatment.

[Urethral diverticulum. Our casuistic and the literatura review]. / Divertículos uretrales. Revisión de nuestra casuística y de la literatura.

PURPOSE: The possible etiopathogenic factors, symptoms, diagnostic methods, surgical management and complications of the urethral diverticula are reviewed. MATERIALS AND METHODS: A retrospective study of the clinical charts with urethral diverticula diagnosis during the period 1986-2006 was carried out. RESULTS: In the last 20 years a total of 19 patients have been treated for this pathology: 15 females and 4 males. Five of the females started with a sensation of vaginal mass; the rest were diagnosed of micturitional (irritative) syndrome, urinary incontinence or urinary infection. In the case of males, 3 of them had a palpable tumour in the penis. The most used diagnostic method was retrograde and voiding cystourethrography; urethrography with double-occlusion balloon catheter was used in 5 cases and urethroscopy in 4 patients; other techniques of image diagnosis like magnetic resonance imaging were necessary for the most complex cases. The treatment was the excision of the diverticulum, except for one of the females who rejected the treatment. The evolution in all treated women was successful, according to follow up 2 years after the treatment. In males, two of them had complex recurrent diverticula. CONCLUSIONS: Urethral diverticula are nosologic entities of difficult diagnosis, due to their low prevalence and their unspecific clinic, therefore diagnosis is sometimes incidental. The etiopathogenity is acquired in most cases and its surgical treatment is more challenging in males than in females probably linked to the fact that diverticula appear in urethras with previous surgery, endourologic manipulation or associated injuries.

[Spontaneous retroperitoneal hemorrhage: our experience at last 10 years]. / Hemorragia retroperitoneal espontánea: nuestra experiencia en los ultimos 10 años.

INTRODUCTION AND OBJECTIVES: Etiology, clinical features, diagnostic methods and treatment of spontaneous retroperitoneal hemorrhage were analyzed. METHODS: We report 27 cases with diagnosis of spontaneous retroperitoneal hemorrhage treated in our hospital between January 1996 and December 2005. The imaging techniques were abdominal ultrasonography, abdominal CT scan and MRI. RESULTS: The most common cause of retroperitoneal hemorrhage was renal angiomyolipoma rupture in 7 patients. Continuous flank or abdominal pain were the primary symptoms. Abdominal ultrasonography showed hematoma in 81.8% patients, but the actual etiologic diagnosis was ascertained in only 40.9% of them. Retroperitoneal hemorrhage was demonstrated by means of abdominal CT scan in all cases and bleeding origin was established in 92.6% of cases. Ten patients underwent urgent surgery while conservative treatment was attempted in the remaining 17. CONCLUSIONS: In our experience, in cases of spontaneous retroperitoneal hemorrhage, CT scan is the best imaging method to establish the diagnosis and the management of such entity although it will need to be individualized for every case because it depends on the hemodinamic situation and etiologic diagnosis.

[Retroperitoneal malignant fibrous histiocytoma with contiguous organs infiltration]. / Histiocitoma fibroso maligno retroperitoneal con infiltración de organos vecinos.

Retroperitoneal tumours are extremely rare neoplasms, most of them malignant. We described the case of a 48-year-old man with a large retroperitoneal mass detected during the study of a constitutional syndrome. The mass was treated surgerically and pathological diagnosis was malignant fibrous histiocytoma. Literature is reviewed and clinical features, histological findings, radiological techniques and therapeutic management are analyzed.

[Yield diagnosis of the peripheral cores in 10 needle extended prostate biopsy]. / Rentabilidad diagnóstica de los cilindros de los cuernos laterales en las biopsias prostáticas ampliadas a 10 muestras.

OBJECTIVE: To value if the increase in the number of cylinders in the prostate's biopsy raise the diagnostic performance of this test. MATERIAL AND METHOD: In March 2005 we initiate this prospective study with patients who are subject to a first prostate Biopsy by a PSA between 4 and 10 ng/ml and negative rectal touch. Transrectal, echodirected prostatic biopsies with ten punctures are carried out according to the following programme as follows: 6 Biopsies according to classic sextant technique, to what we add 4 cylinders from the most lateral zones of the prostate (lateral horns). The variables are analyzed: Age, Total PSA, Free PSA/Total PSA, prostatic volume and PSA density. RESULTS: We value 90 patients consecutively. Prostatic adenocarcinoma was diagnosed to 37 of the 90 patients, which means that the diagnostic rate of the extended Biopsy reached a 41%. Nevertheless, the rate for the classic sextant Biopsy was 32.3%. These differences are statistically significant (Mcnemar test 0.008); besides, this supposes a 27% increase in the diagnostic rentability. The "extra" cylinders in the lateral horns detected 8 tumours which were not detected in the cylinders of the the sextant, and 5 of them presented a Gleason higher or equal to 6. CONCLUSIONS: In our centre we think that the Biopsy extended to 10 cylinders is an adequate strategy for potential prostatic adenocarcinoma patients who are going to be subject to their first Biopsy. Realizing the clinic relevance of the tumours diagnosed thanks to "extra" cylinders, we do not think that this modality implies an over-diagnosis and consequently an overtreatment of the prostate cancer.

[Prostate biopsy strategies. A review of the literature]. / Estrategias para la biopsia de próstata. revisión de la literatura.

INTRODUCTION: In 1987 transrectal ultrasound was described like the technique for guiding prostate biopsy. Since that time different options of transrectal ultrasound guided prostate biopsy were described. MATERIAL AND METHODS: We did a reviewed of the different techniques and cores distribution in the prostate biopsy, also we describes the patient preparation and the most important complications. RESULTS: The majority of the reviewed showed an increase in the sensibility rates with the extended transrectal ultrasound guided prostate biopsies. These improvements generally are due to the most lateral zones. CONCLUSION: Until now, due to a great experience and a low complications rate, the transrectal ultrasound guided prostate biopsy strategy should be extended respect the classical sextant biopsy with cores from the most lateral zones of the prostate.

[Analysis of the spanish urologists adherence to the recomendations of the guidelines on diagnostic and treatment of urinary incontinence]. / Análisis de la adherencia de los urólogos españoles a las recomendaciones de diagnóstico y tratamiento de las guías de práctica clínica sobre incontinencia urinaria.

OBJECTIVE: [corrected] Data regarding the degree of adherence to urinary incontinence guidelines are not available. The aim of this study was to know how the spanish urologist diagnos and treat urinary incontinence. MATERIAL AND METHODS: This is an opinion poll from 202 urologist underwent in 20 representative meetings of the Spain. The poll consisted of 2 questions about diagnostic and 2 about treatment of urinary incontinence. The anwsers were grouped by ideas. The focal group method dinamized by "structured brain storming" was used. We evaluate the adherence to the incontinence guide lines analizing the agreement between the recommendations and the real practice. We average acording all obtained responses. RESULTS: The adherence were: history 88%, physical examination 78%, blood test 47%, urunalysis 72% and urine culture 67%. The adherence for urodynamic investigation was 23%. The use of symptom and quality of life cuestionares was minority (14% y 26%). The adherence to the right questions about the type of incontinece was very high. An average of 2.7 questions to reach correct diagnoses was needed. A 85% of urologist treat urge compenent of mixed incontinence firstly and 11% the stress component. The 27% considered the availability of drug as the main reason for such prioritization. The adherence of treating urge incontinence with antimuscarics was 98% and of life style interventions 50%. For treating stress urinary incontinence, the adherence to pelvic floor muscle training was 81% and to surgery 53%. CONCLUSIONS: Spanish urologist adherence to incontinence urinary guidelines is far from the ideal. Although this study may have bias, the outcome can be considered as representative of the situation. It is desirable that, in the process of guidelines creation, specific parameters to assess the degree of adherence be designed.

Cultural adaptation to Spanish (Spain) of the "Overactive Bladder - Family Impact Measure (OAB-FIM)" questionnaire. / Adaptación cultural al español (España) del cuestionario Overactive Bladder Family Impact Measure (OAB-FIM).

OBJECTIVE: The OAB-FIM was developed as a measure of the impact of an overactive bladder (OAB) on relatives who live with the patient. The objective of this study was conduct a cultural adaptation to Spanish (Spain) of the OAB-FIM questionnaire. METHODS: The adaptation included a conceptual and linguistic validation phase, as well as a phase for measuring the psychometric properties in 25 relatives [mean age, 63.0 years (SD, 14.3); 44% women] who regularly live with patients with OAB, who are of either sex and 18 years of age or older. We measured conceptual and linguistic equivalence, internal reliability, construct validity and content validity. We assessed the applicability and administration load. RESULTS: The OAB-FIM was conceptually and linguistically equivalent to the original, maintaining its 6 domains: social, travel, worry, irritability, sleep and sex. The interagreement correctly placed all items in their domain, except for number 10, which was placed more in worry than in irritability, motivates its reformulation. Some 2.95% of the items were missing. The floor and ceiling effects of the items varied, respectively, between 20-28%, and 0-16%. The mean time for completing the questionnaire was 5.2minutes (SD, 2.8), and 24% of the participants required some type of assistance. The α-Cronbach coefficient varied between 0.948-0.839. The correlations with similar scales in the family were moderate-high (0.407-0.753) or small-moderate with those administered to the patient (0.004-0.423). CONCLUSION: We obtained a Spanish (Spain) version of the OAB-FIM that was conceptually and linguistically equivalent to the original. The questionnaire showed good internal consistency, content and construct validity and applicability.

[Comparative study between tobramicin and tobramicin plus ciprofloxacin in transrectal prostate biopsy prophylaxis]. / Estudio comparativo entre tobramicina y tobramicina más ciprofloxacino como profilaxis para la biopsia transrectal de próstata.

INTRODUCTION AND OBJECTIVES: To compare the efficacy of tobramicin and tobramicin + ciprofloxacin for prevention of transrectal prostatic biopsy infectious complications. We revised our complications, microorganism most common in the infectious complications, and their sensibility. MATERIAL AND METHODS: Prospective and randomized study in 153 patients with 157 prostatic biopsies. The 71 patients in group A were treated with intramuscular tobramicin 100 mg, one dose 30 minutes before biopsy and another one 8 hours afterwards. The 85 patients in group B were treated with the same tobramicin doses and oral ciprofloxacin 500 mg, one dose 30 minutes before biopsy and afterwards they continue with the ciprofloxacin every 12 hours during 3 days. RESULTS: we did 71 biopsies in group A and 86 in group B. 50 (31,8%) patients had hematuria, 20 (12,7%) fever, 15 (9,5%) hemospermia, 7 (4,4%) perineal pain, one (1,2%) orchiepididymitis and another one (1,2%) urinary retention. The patients who had fever were 15 of the group A and 5 of the group B (p=0,004). A total of 15 (21,1%) patients with fever of the group A needed to be treated in the hospital and 3 patients (3,5%) of the group B (p=0,0006). E. coli growthed in 67% of the blood cultures and amoxicillin-clavulanic, tobramicin and third generation of cephalosporins were the antibiotics more eficacious. CONCLUSIONS: Prophylaxis scheme with tobramicin plus ciprofloxacin was more efficacy that tobramicina alone in transrectal prostatic biopsy. Hematuria was the most common complication. E. coli was the microorganism most frequent in infectious complications after prostatic biopsy and amoxicillin-clavulanic, tobramicin and third generation of cephalosporins the most effective antibiotics in our hospital.

OnabotulinumtoxinA in overactive bladder: Evidence-based consensus recommendations.

OBJECTIVE: To offer a set of useful recommendations for urologists who are starting to provide treatment of overactive bladders with onabotulinumtoxinA. METHODS: A literature search to December 2013 was conducted, as well as a subsequent critical reading of the selected publications. The coordinators prepared a document that was submitted for review by the members of the Spanish Group for the use of Botulinum Toxin in Urology. RESULTS: The expert group considered that onabotulinumtoxinA may be used for overactive bladder syndrome with urinary urge incontinence secondary to neurogenic or idiopathic detrusor overactivity for patients for whom conservative treatment and first-line medical treatment has failed, is not tolerated or is contraindicated. Treatment in most cases was performed with local intravesical anesthesia, although it can also be performed under epidural or general anesthesia. Patients must be informed of the possibility of requiring self-catheterization or temporary catheterization. Clinicians should ensure that the patients are capable of performing this catheterization before the treatment is conducted. Patients must also be informed of the need for antibiotic prophylaxis to reduce the risk of urinary tract infections. At least 2 follow-up visits are recommended: the first at days 7-14 after the injection and the second at 2-3 months. Reinjection is indicated when the effect of the treatment decreases. CONCLUSION: These guidelines can help clinicians in their daily decisions and limit the potential risks associated with the incorrect use of the drug.

Diagnostic performance of power doppler and ultrasound contrast agents in early imaging-based diagnosis of organ-confined prostate cancer: Is it possible to spare cores with contrast-guided biopsy?

OBJECTIVES: To evaluate the diagnostic performance of gray scale transrectal ultrasound-B-mode US (BMUS), power Doppler (PDUS), and sonographic contrast (CEUS) in early imaging-based diagnosis of localized prostate cancer (PCa) and to compare the diagnostic profitability of randomized biopsy (RB), US-targeted prostate biopsy by means of PDUS and CEUS. MATERIAL AND METHODS: A single-center, prospective, transversal, epidemiological study was conducted from January 2010 to January 2014. We consecutively included patients who an imaging study of the prostate with BMUS, PDUS, and CEUS was performed, followed by prostate biopsy due to clinical suspicion of prostate cancer (PSA 4-20ng/mL and/or rectal exam suggestive of malignancy). The diagnostic performance of BMUS, PDUS, and CEUS was determined by calculating the Sensitivity (S), Specificity (Sp), Predictive values (PV), and diagnostic odds ratio (OR) of the diagnosis tests and, for these variables, in the population general and based on their clinical stage according to rectal exam (cT1 and cT2). PCa detection rates determined by means of a randomized 10-core biopsy scheme were compared with detection rates of CEUS-targeted (SonoVue) 2-core biopsies. RESULTS: Of the initial 984 patients, US contrast SonoVue was administered to 179 (18.2%). The PCa detection rate by organ of BMUS/PDUS in the global population was 38% versus 43% in the subpopulation with CEUS. The mean age of the patients was 64.3±7.01years (95% CI, 63.75-64.70); mean total PSA was 8.9±3.61ng/mL (95% CI, 8.67-9.13) and the mean prostate volume was 56.2±29cc (95% CI, 54.2-58.1). The detection rate by organ of targeted biopsy with BMUS, PDUS, and CEUS were as follows: Global population (10.6, 8.2, 24.5%), stage cT1 (5.6, 4.2, 16.4%), and stage cT2 (32.4, 22.3, 43.5%). Comparing the detection rates of the CEUS-targeted biopsy and randomized biopsy, the following results were obtained: Global population (24.5% vs. 41.8%), stage cT1 (16% vs. 35%), and stage cT2 (43.5% vs. 66.6%), with a p value<0.05. Following the "core-by-core" analysis, the detection rates by core of CEUS-targeted biopsy versus randomized biopsy were: Global population (16% vs. 13%), stage cT1 (30.3% vs. 28%), and stage cT2 (48% vs. 37%), with a p value>0.05. The NNT for CEUS-targeted biopsy was 83.3. CONCLUSIONS: The low sensitivity, specificity, positive predictive and negative predictive values of gray scale-B-mode, PDUS and CEUS represent scant diagnostic performance of these variables in prostate cancer detection. Prostate cancer detection rates yielded by randomized biopsy were superior than the detection rate of targeted biopsy using B-mode, PDUS and CEUS; as a result, randomized biopsy versus CEUS-targeted biopsies cannot be excluded from biopsy strategy plans for the diagnosis of prostate cancer.

We report the urethra and bladder foreign bodies seen in our department from 1976 to September 2004. We review the kind of the foreign bodies, the psychological profile of the patient, the clinical findings, diagnosis and treatment. We also review the literature about this matter.

[Renal and perirenal abscess]. / Abscesos renales y perirrenales.

Renal and perirenal abscesses are rare infections of the urinary tract traditionally caused by Staphylococcus aureus. Today however there is a predominance of abscesses secondary to coliform bacteria such as E. coli. This paper presents a revision of our series over the last ten years (1987-1996). A total of 11 abscesses (3 renal and 8 perinephritic) were recorded. The most frequent symptom for visiting the clinic was back pain. All patients had predisposing associated conditions. The microbiological analysis revealed E. coli in most abscesses. An HIV+ patient had bilateral renal abscess secondary to Aspergillus fumigatus. CAT appears to be the most specific method for imaging diagnosis, and ultranosography is useful not only to guide percutaneous puncture but also in the follow-up of abscesses after antibiotic treatment. Two renal abscesses resolved with parenteral antibiotic therapy and subsequent observation. Three cases required ultrasound guided percutaneous puncture and intravenous antibiotic therapy. Surgical drainage was required in four. A revision of our experience and the recent literature verified the changes that have taken place in the last few years both in the etiopathogenesis as well as the diagnostic and therapeutical methodology of renal and perinephritic abscesses.

[Primary retroperitoneal tumors: our caseload]. / Tumores retroperitoneales primarios: nuestra casuistica.

Primary retroperitoneal tumors are a very uncommon group of neoplasias in urology. Sixty-four primary retroperitoneal tumors admitted and treated in our hospital from january 1974 to october 2000 were reviewed retrospectively. Clinical presentation, diagnostic, treatment and evolution are analyzed. Five cases were benign (7.8%) and the remains malign (92.2%). Mesodermic tumors were the most frequent. Surgery was performed in 59 patients (92.2%). Radical resection was possible in 100% of benign tumors and 44.5% of malignant tumors. Palliative radiotherapy was performed as the only treatment in 3 patients. Two patients received only symptomatic treatment. Adjuvant chemotherapy (32 patients, 50%) and radiotherapy (19 patients, 29.6%) completed the treatment. Benign tumors 5-year global survival was 100%, malignant tumors 1-year survival was 47.4%, 3-year survival 15.2% and 5-year survival 10.1%. Mean survival was 20.15 months. As it's frequent to find an advanced neoplasm at the diagnostic, surgery must be planned with radical intention. Radiotherapy and chemotherapy could be useful in the therapeutic strategy of these tumors with poor prognosis.
