BPH¡]Benign prostate hyperplasia¡^is one of the most common chronic diseases in aging male around the globe. TURP¡]Transurethral Resection of Prostate¡^remains the gold standard procedure of choice in BPH treatment. But limited literatures regarding the late complication of TURP was available. For understanding the long term follow up result after TURP, and predict the risk factors for re-intervention, we accessed the hospital claims for TURP from the National Health Insurance database, utilizing data from 2001 to 2007 , in 2001, 2002, 2003 TURP cases, we followed each cohort for 5 years to evaluate the late complications. We also examined the association between the characteristics of patient, hospital and the long term prognosis. In this study we found that from 2001to 2003, totally 1,225 patients under went TURP surgery, with the average age 71.52 ¡Ó 7.65 years (47-94 years). Among these cases, 140 patients (11.43%) experienced secondary surgery. Of the 140 secondary surgery patients, 71 received a secondary TURP, 35 received urethral stricture related surgery and 34 received bladder neck contracture related surgery. The study revealed both the characteristics of the patient and the hospital did not show significantly effect to the long term prognosis. In prediction the risk factors of the secondary surgery, the logistic regression analysis revealed those hospitals located at the central part of Taiwan compared to those at northern part of Taiwan showed a relative risk of 0.58, a significant trend of lower risk for secondary surgery. Otherwise, except this geographic location difference, other characteristics of the patient and the hospital show no significantly risk to the post-TURP second surgery. Conclusion of our study, the result of TURP surgery in Taiwan was fairly equal to that in advanced countries. Patient comorbidity, treated in different level, ownership hospitals resulted no significant difference in post-TURP prognosis.

Ziele: Trotz ihrer signifikanten Morbidität stellt die transurethrale Resektion der Prostata (TURP) den gold standard dar für die instrumentelle Therapie der durch die benigne Prostatahyperplasie (BPH) bedingten Blasenauslassobstruktion. Mit dem Hochleistungs-Holmium: YAG Laser kann endoskopisch, in einer relativ blutungsarmen Weise, Prostatagewebe enukleiert werden. Wir verglichen die Technik der transurethralen Holmium-Laser-Enukleation der Prostata (HoLEP) mit der Standard-TURP bei der operativen Therapie von Prostataadenomen. Wir präsentieren die perioperativen Daten, die Kurz- und Langzeitergebnisse dieser randomisierten klinischen Studie. Material und Methoden: Insgesamt wurden 200 Patienten mit einer urodynamisch nachgewiesenen benignen Prostataobstruktion bei einem Prostatavolumen kleiner 100g im transrektalen Ultraschall in ein TURP- und HoLEP-Kollektiv randomisiert. Alle Patienten wurden präoperativ und postoperativ nach 1,6, 12, 18, 24 und 36 Monaten durch Erhebung des American Urological Association symptom score und Messung der maximalen Harnflussrate und des Restharns evaluiert. Die perioperativen Daten und die postoperativen Ergebnisse wurden verglichen. Alle Komplikationen wurden vermerkt. Ergebnisse: Bei der HoLEP waren die Katheterzeit, der Krankenhausaufenthalt und der Hämoglobinverlust signifikant geringer, jedoch die Operationszeit signifikant länger als bei der TURP. HoLEP und TURP führten zu signifikanter und anhaltender Verbesserung aller Miktionsparameter, wobei der Restharn bis einschließlich 36 Monate postoperativ in der HoLEP Gruppe signifikant geringer blieb. Auch die perioperative Morbidität war bei der HoLEP kleiner; Kontinenz, Potenz und Spätkomplikation waren in beiden Gruppen ähnlich. Schlussfolgerungen: HoLEP ist mindestens genauso effektiv wie TURP. HoLEP dauert länger, jedoch sind die perioperative Morbidität, Katheter- und Krankenhausdauer geringer. Beide Methoden zeigen befriedigende Langzeitergebnisse mit wenigen Spätkomplikationen. Dies bestätigt die Dauerhaftigkeit des Therapieerfolges dieser 2. Verfahren. / Purpose: Transurethral electrocautery resection (TURP) is generally regarded as the gold standard surgical treatment for bladder outflow obstruction due to benign prostatic hyperplasia (BPH) despite its rather high morbidity. The high powered holmium: YAG laser can be used endoscopically to enucleate prostatic tissue in a relatively bloodless manner. The technique of transurethral holmium laser enucleation of the prostate (HoLEP) was compared to standard TURP for the surgical management of prostate adenomas. We present the perioperative data, short and long-term results of this randomized clinical trial. Materials and Methods: A total of 200 patients with urodynamic obstruction with a prostate less than 100 gm on transrectal ultrasound were randomized into 2 comparable groups and assigned to HoLEP or TURP. All patients were assessed preoperatively and followed prospectively 1, 6, 12, 18, 24, and 36 months postoperatively with an American Urological Association symptom score, peak urinary flow rate and post-void residual measurement. Perioperative data and postoperative outcome were compared. All complications were noted. Results: HoLEP was significantly superior to TURP in terms of catheter time, hospital stay and hemoglobin loss but operative time was significantly longer. HoLEP and TURP resulted in a significant and lasting improvement of all parameters with post-void residual volume still significantly better in the HoLEP group at the 36-month assessment. Perioperative morbidity was less in the HoLEP group; continence, potency and late complications were similar in both groups. Conclusion: HoLEP is at least as effective as TURP. HoLEP takes longer than TURP, but perioperative morbidtity, catheter time and hospital stay is less. Both treatments have satisfactory long term results with a low late complication rate. This confirms the durability of these 2 procedures.

A Hiperplasia Prostática Benigna (HPB) é a doença benigna mais freqüente na terceira idade. A Ressecção Transuretral (RTU) de próstata constitui-se na técnica operatória mais empregada atualmente para o tratamento da HPB. A anestesia para este procedimento possui características próprias, tornando-se um desafio para o anestesiologista o manejo de suas particularidades. Com o objetivo de avaliar a conduta anestésica, comparando técnicas empregadas, drogas e doses, eventuais complicações e respectivos tratamentos, revisou-se 300 prontuários de pacientes submetidos a RTU de próstata no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto (HC-FMRP-USP). Optou-se por dois períodos de quatro anos com intervalo de dez anos entre eles (1989-1992 (período 1) e 1999-2002 (período 2)) para tentar estabelecer uma suposta relação entre a evolução das técnicas anestésicas e a possível redução na incidência de complicações. Foram incluídos no estudo apenas os pacientes portadores de neoplasias benignas da próstata. Algumas características dos pacientes (média de idade e estado físico ASA) foram semelhantes entre os grupos. A média de peso foi superior no período 2. Foram pedidos menos exames pré-operatórios para os pacientes do período 1. Quanto ao tipo de anestesia houve um predomínio absoluto, nos dois períodos, da anestesia regional (sendo que o bloqueio raquidiano foi o mais utilizado). O anestésico local mais empregado foi a bupivacaína nos dois períodos. Observou-se uma maior incidência de falhas nos bloqueios realizados no período 1, com maior índice de conversão para anestesia geral. O fato pode em parte ser atribuído ao não uso de agentes opióides nas punções nessa época, que sabidamente melhoram a qualidade do bloqueio. A duração média do procedimento foi maior no período 2 (considerando 45 minutos como tempo padrão). A incidência de eventos adversos intra-operatórios, como como hipotensão, arritmias cardíacas e hipotermia foi semelhante entre os períodos. No entanto, houve um maior número de pacientes com diagnóstico de infarto agudo do miocárdio no pós-operatório de até 24 horas no período1. Provavelmente esse fato aconteceu pela falta de exames complementares e avaliação cardiológica prévia nos pacientes submetidos à cirurgia nesse período. No tocante as transfusões sangüíneas, a proporção entre os períodos foi semelhante, embora fosse prática costumeira no período 1 que os pacientes realizassem autotransfusão prévia. A autotransfusão não se mostrou eficaz, na população estudada, como fator redutor do número de transfusões sangüíneas. Na sala de recuperação anestésica o tempo de permanência foi semelhante entre os períodos, no entanto, observou-se uma maior incidência de eventos adversos no período 1. A mortalidade foi maior no período 2 mas essa diferença não foi estatisticamente significante. Palavras- chave: 1. Anestesia 2. Hiperplasia Benigna da Próstata 3.

Transurethral Resection of the Prostate (TRP) is the surgery technique most frequently used for the treatment of BPH. Anaesthesia for this procedure has its own features becoming a challenge for the anaesthesiologist to manage with its peculiarities. In order to evaluate the anaesthetic behavior, to compare the techniques used, drugs and doses, possible complications and their treatments, three hundreds of medical records of patients submitted to TRP in the University Hospital, Faculty of Medicine of Ribeirão Preto (FM-USP). Two periods of four years were chosen (1989-1992 (period 1) and 1999-2002 (period 2)) in order to establish some evolution between the anaesthetics techniques used and possible reduction in the incidence of complications. Only patients who had benign prostatic hyperplasia were included in this study. Some patients characteristics were similar between the two groups (mean ages and physical status ASA). Mean weight were higher in the period 2. Less preoperative exams were applied in the period 1. In both periods, the regional anaesthesia was predominant (the spinal anaesthesia was the most used). Hyperbaric bupivacaine was the most commonly used agent for regional anaesthesia in both periods. More failed blocks were seen in the period 1 with an increased number of conversion to general anaesthesia. This fact may be attached with the lack of use of opioids agents in that period, which are known to complement and improve the quality of the block. Mean duration of the procedure were higher in period 2 (taking 45 minutes as standard time). The incidence of intra-operative adverse events like hypotension, cardiac arrhythmias and hypothermia were similar in both periods. However more patients had acute heart infarct in the 24 hours of postoperative period 1. Probably this happens because of the lack of preoperative exams and cardiology evaluation in patients submitted to surgery in this period. The proportion of blood transfusions were similar in two periods although it was usual to make an autotransfusion in the patients of the first period. Autotransfusion previous to the surgery were not an effective method to reduce the number of transfusions. In postanaesthesia care unit the length of stay was similar between the periods but the incidence of adverse events was higher in the period 1. The mortality was bigger in the period 2 but this difference were not significant. Key-words: 1. Anaesthesia 2. Benign Prostatic Hyperplasia 3. Transurethral Resection of the Prostate 4.
