Documento de consenso sobre pautas de actuación y seguimiento del varón con síntomas del tracto urinario inferior secundarios a hiperplasia prostática benigna / Consensus document on the management and follow-up of the male with lower urinary tract symptoms secondary to benign prostate hyperplasia

La hiperplasia benigna de próstata (HBP) es una patología con una alta incidencia. Su diagnóstico y tratamiento son compartidos entre urólogos y médicos de atención primaria. Su manejo consume una enorme cantidad de recursos. La Sociedad Española de Médicos de Atención Primaria (SEMERGEN), la Sociedad Española de Médicos Generales y de Familia (SEMG), la Sociedad Española de Medicina de Familia y Comunitaria (semFYC) y la Asociación Española de Urología (AEU) han elaborado un documento sobre pautas de actuación y seguimiento de la HBP, presentado aquí de manera resumida, en el que se pretende actualizar las guías anteriormente publicadas, en base a las últimas evidencias. Estas nuevas recomendaciones tienen como objetivo principal sensibilizar al médico de atención primaria y ayudarle en la evaluación diagnóstica, el tratamiento y el seguimiento, además de aportar criterios unificados y consensuados de derivación al segundo nivel asistencial (AU)

Benign prostate hyperplasia (BPH) is a high-incidence condition. Its diagnosis and treatment is shared between urologists and Primary Care physicians. Its management uses up a significant amount of resources. The Spanish Society of Primary Care Physicians (SEMERGEN), the Spanish Society of General Practitioners and Family Doctors (SEMG), the Spanish Society of Family and Community Medicine (semFYC), and the Spanish Association of Urology (AEU) have prepared a document on the management and monitoring of BPH, in which the aim is to incorporate the latest evidence in order to update the previously published guidelines, and present them here in condensed form. The main objective of these new recommendations is to raise the awareness of Primary Care physicians and assist them in its diagnostic evaluation, treatment and monitoring, as well as providing unified consensus criteria for referral to the secondary care level (AU)

[Influence of drugs on urological diseases]. / Einfluss von Medikamenten auf urologische Krankheiten.

A number of drugs prescribed for the treatment of various diseases can induce urological symptoms as side effects. Antihypertensive drugs (particularly alpha blockers) can result in stress incontinence, whereas selective serotonin reuptake inhibitors (SSRI) can cause urge incontinence and estrogen promotes both forms. A wide range of drugs with anticholinergic activity, among them neuroleptics, tricyclic antidepressants and certain drugs used in airway disorders are associated with urinary retention. Only very few drugs bear a relevant risk for urolithiasis, i. e. the diuretic triamterene and protease inhibitors, such as indinavir; however, the widely used combination of calcium and vitamin D supplementation for prevention of osteoporosis may be an underdiagnosed cause of renal calculi. Drug-induced sexual dysfunction is a frequent side effect of antihypertensive treatment, particularly with beta adrenoceptor blockers and diuretics. The SSRI and some neuroleptics can also impair sexual function.

Significance of urinary tract involvement in patients treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

BACKGROUND: Urinary tract involvement in patients with peritoneal surface disease treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) often requires complex urologic resections and reconstruction to achieve optimal cytoreduction. The impact of these combined procedures on surgical outcomes is not well defined. METHODS: A prospective database of CRS/HIPEC procedures was analyzed retrospectively. Type of malignancy, performance status, resection status, hospital and intensive care unit stay, morbidity, mortality, and overall survival were reviewed. RESULTS: A total of 864 patients underwent 933 CRS/HIPEC procedures, while 64 % (550) had preoperative ureteral stent placement. A total of 7.3 % had an additional urologic procedure without an increase in 30-day (p = 0.4) or 90-day (p = 1.0) mortality. Urologic procedures correlated with increased length of operating time (p < 0.001), blood loss (p < 0.001), and length of hospitalization (p = 0.003), yet were not associated with increased overall 30-day major morbidity (grade III/IV, p = 0.14). In multivariate analysis, independent predictors of additional urologic procedures were prior surgical score (p < 0.001), number of resected organs (p = 0.001), and low anterior resection (p = 0.03). Long-term survival was not statistically different between patients with and without urologic resection for low-grade appendiceal primary lesions (p = 0.23), high-grade appendiceal primary lesions (p = 0.40), or colorectal primary lesions (p = 0.14). CONCLUSIONS: Urinary tract involvement in patients with peritoneal surface disease does not increase overall surgical morbidity. Patients with urologic procedures demonstrate survival patterns with meaningful prolongation of life. Urologic involvement should not be considered a contraindication for CRS/HIPEC in patients with resectable peritoneal surface disease.

Nabiximols in the treatment of spasticity, pain and urinary symptoms due to multiple sclerosis.

INTRODUCTION: Over the last two decades, experimental and clinical data suggest a therapeutic benefit of cannabis-based medicines for a variety of multiple sclerosis (MS) symptoms. Clinical trials, both with synthetic or plant-derived cannabinoids, have demonstrated clinical efficacy of cannabinoids for the treatment of spasticity, neuropathic pain and bladder dysfunction. Nabiximols, a 1:1 mix of delta-9-tetrahydrocanabinol and cannabidiol extract from cloned chemovars, was licensed in the UK in 2010 and has also been approved in other European countries and Canada. The European Federation of Neurological Societies recommends that cannabis should be used only as a second or third line treatment in central neuropathic pain. AREAS COVERED: After a brief discussion of the endocannabinoid system, this review focuses on the use of cannabis to improve MS symptoms. More specifically, the authors have analyzed clinical studies on cannabis-based medicine extract (CBME), in particular nabiximols, in spasticity, as well as pain, and bladder dysfunction in MS. The authors have considered the large randomized controlled trials examining the psychological effects associated with cannabinoids use as well as long-term follow-up studies. EXPERT OPINION: Despite a number of trials with very promising results, there are still concerns related to relative paucity of data on long-term safety. Also, the long-term efficacy information in terms of the control of symptoms of a disease in which the natural history is progression is sparse. Therefore, further studies are required to improve the current knowledge of nabiximols.

Diagnóstico y evolución de las malformaciones congénitas del riñón y vías urinarias: 1999-2005: Holguín 2007 / Diagnosis and evolution of congenital malformations of the kidney and urinary tract

Con el objetivo de evaluar la experiencia clínica en los Servicios de Nefrología y Urología del Hospital Pediátrico Provincial Docente Octavio de Concepción y de la Pedraja de Holguín se realizó un estudio descriptivo de 351 pacientes atendidos entre enero 1999 y diciembre 2005. En esta serie de 351 pacientes fueron diagnosticadas 535 malformaciones congénitas del riñón y vías urinarias de 19 tipos. El reflujo vesico ureteral primario, la estenosis de la unión ureteropiélica y el doble sistema excretor fueron en ese orden, las malformaciones más frecuentes, siendo la edad más común de diagnóstico durante el primer año de vida. La mayoría de los pacientes se presentaron con infección del tracto urinario y un número importante fueron asintomáticos. La ultrasonografía y la uretrocistografía miccional convencional resultaron una combinación efectiva para el diagnóstico de estas. La mayoría de los pacientes a los que se les realizó diagnóstico prenatal tenían una Hidronefrosis Congénita. La valva de uretra posterior fue la principal causa de insuficiencia renal crónica. Los grados I, II y III de reflujo vesico ureteral primario casi siempre desaparecen espontáneamente, siendo el tratamiento médico o conservador la piedra angular en el manejo de estos pacientes. Apreciamos una relación directa entre la nefropatía de reflujo y el grado de esta entidad.

A proposed set of ethical practice guidelines in the assessment and treatment of pelvic floor disorders.

The treatment of pelvic floor disorders using biofeedback, behavioral therapies, and other applied psychophysiological treatments has been well documented as effective. Practitioners must take due care to ensure that they practice within the boundaries of what is common practice for their discipline and within the scope of practice allowed by their professional license as outlined by the appropriate state licensing law(s), the ethical principles and practice guidelines and standards for their discipline, and those of the Association of Applied Psychophysiology and Biofeedback if using a biofeedback assessment or treatment. Being competent to provide a particular treatment does not necessarily make it legal and/or ethical. This paper provides a set of recommended practice guidelines for use in the assessment and treatment of pelvic floor disorders. Please note that they have not at this time been endorsed as an official position of the Association of Applied Psychophysiology and Biofeedback or any other professional organization.

Lower urinary tract symptoms and erectile dysfunction; links for diagnosis, management and treatment.

Recent large-scale epidemiological studies have documented a strong association between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED). This observation has two important scientific and clinical aspects: (i) to reveal the pathomechanism linking LUTS and ED and (ii) to consider this fact in the individual approach for diagnosis and management of these two disorders. The following hypotheses are under investigation to explain the relation between LUTS and ED: (i) an increased Rho-kinase activation, (ii) an alpha-adrenergic receptor imbalance, (iii) a decrease of NOS/NO in the endothelium, (iv) atherosclerosis affecting the small pelvis and (v) an autonomic hyperactivity, each affecting simultaneously bladder, prostate and penis. According to a recent randomized trial, sildenafil has a positive effect on LUTS yet not on uroflowmetry in men with LUTS and ED. Although further trials are mandatory, phosphodiesterase-5 inhibitors might play a role in the management of LUTS in the future. alpha-Blockers have no relevant effect on erectile function, tamsulosin leads to retrograde ejaculation in up to 10%. 5alpha-Reductase inhibitors are associated with ED, loss of libido and reduction of ejaculate volume in up to 10%. Transurethral and open prostatectomy induce retrograde ejaculation in up to 90% of patients while their impact on erectile function is still controversially discussed. Minimal invasive treatment options (laser prostatectomy, transurethral microwave thermotherapy) have a lower rate of retrograde ejaculation in the range of 20-70%. LUTS and ED are strongly linked although the exact mechanism is poorly understood. Men seeking for help for LUTS/benign prostatic hyperplasia should be assessed for different aspects of sexual dysfunction and informed regarding the impact of medication and surgery on sexual health.

A 15-year longitudinal analysis of trends in elective urological surgery - an evidence base for Modernising Medical Careers.

INTRODUCTION: The impact of Modernising Medical Careers on the differential need for consultant urologists and urological surgeons is as yet unknown. This study's aim was to determine what changes there had been in operative urological activity so as to predict the need for urological surgeons in the future. MATERIALS AND METHODS: A retrospective study of all elective operative urological surgery over a 15-year period was performed. The absolute numbers of patients presenting for different grades of surgery were aggregated and analysed using the Spearman's rank correlation test. RESULTS: Aggregated data from 27,839 procedures demonstrated no change in the number of operations (r 0.01; NS) or the number of diagnostic endoscopic procedures (r 0.21; NS) carried out over the study period. There was a decrease in endoscopic surgery related to a 70% reduction in trans-urethral resection of the prostate (TURP) (r -0.89; P = <0.0001) and an increase in ureteroscopic interventions (r 0.82; P = 0.0002) for stone disease. There was no change in the amount of major surgery carried out (r -0.43; NS) over the 15 years. CONCLUSIONS: There have been changes to the pattern of surgery urologists have provided over the last 15 years but the need for complex surgical interventions has not altered. This suggests there will be as great a need for operating surgeons in the future, as currently exists.

Falso residuo postmiccional diagnosticado por videourodinamia / False postvoid residual volume diagnosed by videourodynamics

Presentamos un caso de un paciente varón joven diagnosticado de reflujo vésico ureteral bilateral. En el estudio urodinámico se objetiva una posible disinergia vesico-esfinteriana no neurógena, con gran residuo postmiccional. Tras tratamiento con biofeedback se soluciona la disinergia, persistiendo el gran residuo. El estudio con videourodinamia permitió diagnosticar la presencia de un falso residuo postmiccional causado por el vaciamiento ureteral del reflujo bilateral masivo

We present a case report of a young male patient, with a bilateral vesico renal reflux. The urodynamic study findings suggested the possibility of a non-neurogenic bladder-external spincter dissinergya producing a valuable residual volume. After biofeedback treatment, the dissinergia disappeaed, but residual volume persisted. The videourodynamic assessment allowed us the accurate diagnosis of a false residual volume, produced by the voiding of the refluxed urine from the ureters into the bladder

Natural history of lower urinary tract symptoms in men--result of a longitudinal community-based study in Japan.

OBJECTIVES: To investigate the longitudinal changes in the International Prostate Symptom Score (IPSS), bother score, and quality-of-life index in a community-based study in Japan. Of 289 men between 40 and 79 years of age who were analyzed in the first community-based study, 223 (77.2%) participated in a follow-up study conducted 3 years later. The IPSS, bother score, and quality-of-life index, as well as medical histories and current medication use, were evaluated. RESULTS: Neither the average IPSS, bother score, nor quality-of-life index significantly changed after 3 years in any age decade. However, changes in the IPSS varied among individuals, because 32%, 35%, and 33% of the men reported improved, stable, and worsened IPSS, respectively. Transurethral resection of the prostate was performed on 0%, 4%, and 21% of the men in the mild (0 to 7), moderate (8 to 19), and severe (20 to 35) IPSS categories, respectively. Neither prostate volume nor peak urinary flow rate significantly predicted progression of the IPSS after 3 years. CONCLUSIONS: Although no definite general symptomatic progression was observed in the participants during 3 years, changes in subjective urinary symptoms varied among individuals ranging from improvement to worsening. The men with a more severe IPSS had a greater chance of transurethral resection of the prostate within 3 years.

Preoperative work-up of early cervical cancer (stages Ib-IIa).

OBJECTIVE: To determine the effectiveness of preoperative investigations in early cervical cancer. MATERIALS: We retrospectively reviewed the medical records of 309 patients with previously untreated early cervical carcinoma who completed pretreatment evaluation at "St. Savas" Cancer Hospital of Athens and "Metaxas" Memorial Hospital of Peireas between January 1986 and September 1, 2000. Ages ranged from 18-77 years old with a mean age of 48 and S.D. of 12.25. FIGO staging was Ib (200 pts.), IIa (105 pts.), IV (4 pts.). Histologic type was squamous (267 pts.), adenoid (35 pts.), adenosquamous (7 pts.). The patients were clinically examined and routinely evaluated with blood work-up, chest X-ray, IVP, abdominal CT scan, barium enema, sigmoidoscopy, cystoscopy, and/or urine cytology. Patients with early stage cervical carcinoma were treated with Wertheim-Meigs radical hysterectomy and pelvic lymphadenectomy, while those with advanced stage cervical carcinoma were treated with radiotherapy and chemotherapy. RESULTS: In urinary tract investigation, CT showed a sensitivity of 100% and a specificity of 99.67%. In gastrointestinal tract investigation CT showed a sensitivity of 50% and a specificity of 99.67%. When we compared the histologic findings of the pelvic lymph nodes that were extracted in surgically treated patients with the preoperative CT findings, we found that CT had a sensitivity of 63.33% and a specificity of 88.57%. CONCLUSION: In our series of patients with early stage cervical carcinoma, imaging and endoscopic tests added limited information over pelvic examination and altered in four cases (1.29%) the choice of the appropriate treatment modality. CT scans proved adequate in this series of patients in the evaluation of the bladder and colon. All other tests could have been performed only when CT was suspicious of invasion. Moreover, CT served as a baseline examination for future comparative studies in the follow-up of patients.

Predictive factors for sacral neuromodulation in chronic lower urinary tract dysfunction.

OBJECTIVES: To investigate data from 211 patients who underwent a trial stimulation (percutaneous nerve evaluation [PNE]) to determine the clinical parameters that can enhance the prediction of PNE success. The advantageous effect of sacral neuromodulation depends on the accurate identification of suitable candidates during the preimplantation PNE. METHODS: A total of 211 patients (161 women and 50 men), with refractory urge incontinence, urgency-frequency syndrome, and urinary retention, underwent a PNE. Patient data (demographics, medical history, urologic investigations, and diagnosis) were collected. The PNE results were evaluated from a voiding diary and patient history. More than 50% improvement of voiding parameters was considered a successful PNE, and those patients were selected for implantation. Logistic regression analysis was performed. The factors tested for predicting the test result were sex, patient age, diagnosis, previous surgery, neurogenic bladder dysfunction, duration of complaints, and previous treatments. RESULTS: The PNEs were positive in 85 patients (40.3%) and negative in 105 patients (49.8%). In 18 patients (8.5%), the test electrode had migrated; 3 more patients were not assessable and were also excluded. Missing data on the variable "duration of complaints" reduced the number of patients in the analyses from 190 to 174 patients. CONCLUSIONS: Intervertebral disk prolapse, duration of complaints, neurogenic bladder dysfunction, and urge incontinence were found to be significant predictive factors. However, a PNE remains necessary to evaluate a patient's chance of implant success objectively.

Quality of life and alpha-blocker therapy: an important consideration for both the patient and the physician.

Symptom severity and the impact of lower urinary tract symptoms (LUTS) on quality of life (QOL) are the usual reasons that patients with benign prostatic hyperplasia (BPH) seek medical care. Various questionnaires have been developed to assess symptom severity and to gauge the impact of these symptoms on QOL. These instruments have been validated in studies and are used to compare agents used to treat LUTS in patients with BPH. Studies have shown that as the severity of LUTS increases, so does the impact on a patient's QOL. Tools have also been developed to assess sexual function in patients with BPH who frequently manifest erectile dysfunction. Treatment of LUTS in patients with BPH should be evaluated for the effect on symptom severity, QOL, and sexual function.
