OBJECTIVES@#To investigate the effect of progressive pre-disconnection of urethral mucosal flap during transurethral plasmakinetic enucleation of prostate (TUPEP) on early recovery of urinary continence.@*METHODS@#Clinical data of patients with benign prostatic hyperplasia (BPH) admitted in Zhujiang Hospital of Southern Medical University during February and May 2022 were collected. All the patients underwent TUPEP, and the progressive pre-disconnection of urethral mucosal flap was performed in the procedure. The total operation time, enucleation time, postoperative bladder irrigation time and catheter indwelling time were recorded. Urinary continence was evaluated 24 h, 1 week, and 1, 3, 6 months after the removal of urinary catheter.@*RESULTS@#All surgeries were successfully completed at one time with less intraoperative bleeding, and there were no complications such as rectal injury, bladder injury or perforation of prostate capsule. The total operation time was (62.2±6.5) min, the enucleation time was (42.8±5.2) min, the postoperative hemoglobin decrease by (9.5±4.5) g/L, the postoperative bladder irrigation time was (7.9±1.4) h, and the postoperative catheter indwelling time was 10.0 (9.2, 11.4) h. Only 2 patients (3.6%) had transient urinary incontinence within 24 h after catheter removal. No urinary incontinence occurred at 1 week, and 1, 3, 6 months after operation, and no safety pad was needed. The Qmax at 1 month after operation was 22.3 (20.6, 24.4) mL/s, international prostate symptom scores were 8.0 (7.0, 9.0), 5.0 (4.0, 6.0) and 4.0 (3.0, 4.0) at 1, 3 and 6 months after surgery, and quality of life scores at 1, 3 and 6 months after surgery were 3.0 (2.0, 3.0), 2.0 (1.0, 2.0) and 1.0 (1.0, 2.0), all of these indicators were better than those before surgery (all P<0.01).@*CONCLUSIONS@#In the treatment of BPH, the application of progressive pre-disconnection of urethral mucosal flap in TUPEP can completely remove the hyperplastic glands and promote early recovery of postoperative urinary continence with less perioperative bleeding and decreased surgical complications.

Reporte de caso: Bloqueo del erector de la espina en resección transuretral de próstata / Case report: Erector spine block for transuretral prostatic resection

The Erector Spinae Plane (ESP) block, described in 2016 by Dr. Forero et al, was used to treat neuropathic pain and postoperative acute pain. It was described as an interfascial block in the erector spinae plane, where it manages to block both ventral and dorsal branches of the spinal nerve. Due to scarce literature on its applicability in urological endoscopic surgeries, we formulate the hypothesis that it would be an effective opioid-sparing analgesic alternative in patients undergoing TULIP. Therefore, bilateral ESP was performed in a 69-year-old patient, who underwent transurethral prostatectomy guided by laser induced (TULIP) for benign prostatic hyperplasia. The patient did not require rescue medication, reported a maximum VAS of 4/10. At 72 hours postoperatively, the patient kept a VAS of 0/10, without nausea and vomiting, with a Likert satisfaction level of 1

El bloqueo del plano erector de la espina (ESP) fue descrito en 2016 por el Dr. Forero et al., con el afán de tratar el dolor neuropático y el dolor agudo posoperatorio. Consiste en un bloqueo interfascial en el plano del erector de la espina, en el cual se logra el bloqueo tanto de ramas ventrales como dorsales de los nervios espinales. Debido a la falta de literatura sobre su indicación en cirugías endoscópicas urológicas se formula la hipótesis de que podría considerarse como una alternativa analgésica efectiva ahorradora de opioides en pacientes sometidos a RTU-P. Por lo anterior se realizó el bloqueo ESP de manera bilateral a un paciente de 69 años, el cual fue sometido a prostatectomía transuretral guiado por láser inducido (TULIP) por hiperplasia prostática benigna. El paciente no requirió opioides de rescate, con EVA 0/10 en posoperatorio, valor que se mantuvo de la misma manera por 72 h, tanto en reposo como en movimiento, sin la presencia de náuseas o vómitos y una escala de satisfacción de Likert de 1.

¿Resección transuretral bipolar o monopolar para hiperplasia prostática benigna? / Bipolar or monopolar transurethral resection for benign prostatic hyperplasia?

INTRODUCCIÓN: La resección transuretral es el método de elección para la resolución endoscópica de la uropatía obstructiva baja por hiperplasia benigna de la próstata menor a 80cc. Tradicionalmente esta ha sido realizada con asas de resección que utilizan energía monopolar. El uso de energía bipolar ha desplazado la tecnología precedente en el último tiempo. Se dispone a evaluar la eficacia y seguridad de ambas tecnologías para la técnica. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos 13 revisiones sistemáticas que en conjunto incluyen 32 estudios primarios, de los cuales 31 corresponden a ensayos aleatorizados. Concluimos que, si bien podrían no existir diferencias de eficacia entre ambas técnicas, la utilización de energía bipolar disminuye la incidencia de síndrome post resección transuretral y probablemente disminuye el riesgo de sangrado que requiere transfusión.

INTRODUCTION: Transurethral resection is currently considered as standard endoscopic treatment for lower urinary tract obstruction due to benign hyperplasia under 80 cc. Monopolar resection loops has been traditionally used but bipolar energy has recently displaced precedent technology. The purpose of this summary is to evaluate the efficacy and safety of both technologies. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified 13 systematic reviews including 32 primary studies, among them 31 randomized trials. We concluded although there may be no difference in terms of efficacy among both techniques, the use of bipolar energy reduces the incidence of transurethral resection syndrome and probably reduces the risk of bleeding that requires red blood cell transfusion.

Anestesia subaracnoidea con dosis variables de bupivacaina con fentanilo, en la resección transuretral de la próstata / Subarachnoid anesthesia with variable doses of bupivacaine with fentanyl in the trans-urethral resection of the prostate

Introducción: en la actualidad se han descrito diversos modelos de raquianestesia con bupivacaína a dosis diferentes, asociadas o no con fentanilo, que proveen de una anestesia segura y eficaz, disminuyen la intensidad de dolor posquirúrgico, preservan la función cognoscitiva, y reduce las complicaciones atribuidas a la lidocaína hiperbárica por neurotoxicidad. Objetivo: evaluar el efecto de bajas dosis de bupivacaína con fentanilo para anestesia subaracnoidea en pacientes sometidos a resección transuretral de próstata. Materiales y Métodos: se realizó un estudio descriptivo cuantitativo, longitudinal, prospectivo en 200 pacientes programados para dicha cirugía e indicación de anestesia subaracnoidea con bupivacaína, los cuales fueron distribuidos de forma aleatoria en cuatro grupo. Resultados: tanto el bloqueo sensitivo como motor fue más rápido en los pacientes de los Grupos B (3,0; 11,2) y (7,1; 8,3), Grupo C (5,0; 9,4) y (6,2; 9,4) y Grupo D (6,1; 8,3) y (4,7; 10,9); mientras que el Grupo A fue de (6,0; 8,5) y (9,9; 11,7), respectivamente. Se observó que en la totalidad de los pacientes de los Grupos C y D se obtuvo anestesia de buena calidad. Conclusiones: la administración intratecal de 7,5 mg de bupivacaina con 25 µg de fentanilo produjo anestesia satisfactoria, disminuyó el periodo de latencia, mantuvo mejor estabilidad hemodinámica, prolongó la analgesia postoperatoria y se asoció a menor incidencia de complicaciones peri operatorias (AU).

Introduction: currently, several models of spinal anesthesia with bupivacaine in different doses, associated or not to fentanyl, have been described providing a safe and efficacious anesthesia, reducing the intensity of the postsurgical pain, preserving the cognitive function, and reducing the complications attributed to hyperbaric lidocaine due to its neurotoxicity. Aim: to assess the effect of low doses of bupivacaine with fentanyl as subarachnoid anesthesia in patients undergoing a prostate trans-urethral resection. Materials and Methods: a prospective, longitudinal, quantitative, descriptive study was carried out in 200 patients programmed for that kind of surgery and with the indication of subarachnoid anesthesia through bupivacaine; they were randomly distributed in four groups. Outcomes: both, the sensory block and the motor one were faster in the patients of the Group B (3,0; 11,2) and (7,1; 8,3), Group C (5,0; 9,4) and (6,2; 9,4) and Group D (6,1; 8,3) and (4,7; 10,9); while in the patients of the Group A they were (6,0; 8,5) y (9,9; 11,7) respectively. It was observed a good quality anesthesia in all the patients of the Groups C and D. Conclusions: the intrathecal administration of 7,5 mg of bupivacaine with 25 µg of fentanyl produced a satisfactory anesthesia, reduced the latency period, kept a better hemodynamic stability up, extended the post-surgery analgesia and was associated to fewer incidences of perioperative complications (AU).

Evaluation of the learning curve for transurethral plasmakinetic enucleation and resection of prostate using a mentor-based approach

ABSTRACT Objective To analyze the mentor-based learning curve of one single surgeon with transurethral plasmakinetic enucleation and resection of prostate (PKERP) prospectively. Materials and Methods Ninety consecutive PKERP operations performed by one resident under the supervision of an experienced endourologist were studied. Operations were analyzed in cohorts of 10 cases to determine when a plateau was reached for the variables such as operation efficiency, enucleation efficiency and frequency of mentor advice (FMA). Patient demographic variables, perioperative data, complications and 12-month follow-up data were analyzed and compared with the results of a senior urologist. Results The mean operative efficiency and enucleation efficiency increased from a mean of 0.49±0.09g/min and 1.11±0.28g/min for the first 10 procedures to a mean of 0.63±0.08g/min and 1.62±0.36g/min for case numbers 31-40 (p=0.003 and p=0.002). The mean value of FMA decreased from a mean of 6.7±1.5 for the first 10 procedures to a mean of 2.8±1.2 for case numbers 31-40 (p<0.01). The senior urologist had a mean operative efficiency and enucleation efficiency equivalent to those of the senior resident after 40 cases. There was significant improvement in 3, 6 and 12 month’s parameter compared with preoperative values (p<0.001). Conclusions PKERP can be performed safely and efficiently even during the initial learning curve of the surgeon when closely mentored. Further well-designed trials with several surgeons are needed to confirm the results.

Bipolar transurethral enucleation and resection of the prostate versus bipolar resection of the prostate for prostates larger than 60gr: A retrospective study at a single academic tertiary care center

ABSTRACT Objective: To evaluate the efficacy and safety of bipolar transurethral enucleation and resection of the prostate (B-TUERP) versus bipolar transurethral resection of the prostate (B-TURP) in the treatment of prostates larger than 60g. Material and Methods: Clinical data for 270 BPH patients who underwent B-TUERP and 204 patients who underwent B-TURP for BPH from May 2007 to May 2013 at our center were retrospectively analyzed. Outcome measures included operative time, decreased hemoglobin level, total prostate specific antigen (TPSA), International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), quality of life (QoL) score, post void residual urine volume (RUV), bladder irrigation duration, hospital stay, and the weight of resected prostatic tissue. Other measures included perioperative complications including transurethral resection syndrome (TURS), hyponatremia, blood transfusion, bleeding requiring surgery, postoperative acute urinary retention, urine incontinence and urinary sepsis. Patients in both groups were followed for two years. Results: Compared with the B-TURP group, the B-TUERP group had shorter operative time, postoperative bladder irrigation duration and hospital stay, a greater amount of resected prostatic tissue, less postoperative hemoglobin decrease, better postoperative IPSS and Qmax, as well as lower incidences of hyponatremia, urinary sepsis, blood transfusion requirement, urine incontinence and reoperation (P<0.05 for all). Conclusions: B-TUERP is superior to B-TURP in the management of large volume BPH in terms of efficacy and safety, but this finding needs to be validated in further prospective, randomized, controlled studies.

Low-dose-rate brachytherapy for patients with transurethral resection before implantation in prostate cancer. Long-term results

ABSTRACT We analyzed the long-term oncologic outcome for patients with prostate cancer and transurethral resection who were treated using low-dose-rate (LDR) prostate brachytherapy. Methods and Materials: From January 2001 to December 2005, 57 consecutive patients were treated with clinically localized prostate cancer. No patients received external beam radiation. All of them underwent LDR prostate brachytherapy. Biochemical failure was defined according to the "Phoenix consensus". Patients were stratified as low and intermediate risk based on The Memorial Sloan Kettering group definition. Results: The median follow-up time for these 57 patients was 104 months. The overall survival according to Kaplan-Meier estimates was 88% (±6%) at 5 years and 77% (±6%) at 12 years. The 5 and 10 years for failure in tumour-free survival (TFS) was 96% and respectively (±2%), whereas for biochemical control was 94% and respectively (±3%) at 5 and 10 years, 98% (±1%) of patients being free of local recurrence. A patient reported incontinence after treatment (1.7%). The chronic genitourinary complains grade I were 7% and grade II, 10%. At six months 94% of patients reported no change in bowel function.Conclusions: The excellent long-term results and low morbidity presented, as well as the many advantages of prostate brachytherapy over other treatments, demonstrates that brachytherapy is an effective treatment for patients with transurethral resection and clinical organ-confined prostate cancer

Evaluation of holmium laser for transurethral deroofing of severe and multiloculated prostatic abscesses

PURPOSE: Our objective was to evaluate the use of a holmium laser for transurethral deroofing of a prostatic abscess in patients with severe and multiloculated prostatic abscesses. MATERIALS AND METHODS: From January 2011 to April 2014, eight patients who were diagnosed with prostatic abscesses and who underwent transurethral holmium laser deroofing at Pusan National University Hospital were retrospectively reviewed. RESULTS: Multiloculated or multifocal abscess cavities were found on the preoperative computed tomography (CT) scan in all eight patients. All patients who underwent transurethral holmium laser deroofing of a prostatic abscess had successful outcomes, without the need for secondary surgery. Of the eight patients, seven underwent holmium laser enucleation of the prostate (HoLEP) for the removal of residual adenoma. Markedly reduced multiloculated abscess cavities were found in the follow-up CT in all patients. No prostatic abscess recurrence was found. Transient stress urinary incontinence was observed in three patients. The stress urinary incontinence subsided within 3 weeks in two patients and improved with conservative management within 2 months in the remaining patient. CONCLUSIONS: Transurethral holmium laser deroofing of prostatic abscesses ensures successful drainage of the entire abscess cavity. Because we resolved the predisposing conditions of prostatic abscess, such as bladder outlet obstruction and prostatic calcification, by simultaneously conducting HoLEP, there was no recurrence of the prostatic abscesses after surgery. We recommend our method in patients requiring transurethral drainage.

Efficacy and safety of holmium laser enucleation of the prostate for extremely large prostatic adenoma in patients with benign prostatic hyperplasia

PURPOSE: To evaluate the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for extremely large prostates. MATERIALS AND METHODS: Patients undergoing HoLEP between July 2008 and December 2013 from the Seoul National University Hospital Benign Prostatic Hyperplasia Database Registry were retrospectively analyzed. The patients were divided into three groups according to their total prostate volume (TPV): group A (TPV or =200 mL); the clinical data of the three groups were compared. All patients were followed up 2 weeks, 3 months, and 6 months after surgery. RESULTS: A total of 502 patients (group A, 426; group B, 70; group C, 6) with a mean age of 69.0 (standard deviation, +/-7.3) years were included in our analysis. The mean prostate volume and prostate-specific antigen level were 68.7+/-36.9 mL and 4.15+/-4.24 ng/mL, respectively. The enucleation and morcellation times were longer in group C (p<0.001), and the enucleation efficacy was higher in this group (p<0.001, R2=0.399). Moreover, the mean postoperative catheterization and hospitalization periods were significantly longer in group C (p=0.004 and p=0.011, respectively). However, there were no significant differences between the groups in any other postoperative events, including recatheterization, reoperation, urinary tract infection, clot retention, and bladder neck contracture (p range, 0.516-0.913). One patient in group C experienced recurrence of the urethral stricture. CONCLUSIONS: HoLEP in patients with an extremely large prostate can be performed efficiently and safely.

Difference between actual vs. pathology prostate weight in TURP and radical robotic-assisted prostatectomy specimen

Introduction To investigate and highlight the effect of formaldehyde induced weight reduction in transurethral resection of prostate (TURP) and radical robotically-assisted prostatectomy (RALP) specimen as a result of standard chemical fixation. Materials and Methods 51 patients were recruited from January 2013 to June 2013 who either underwent a TURP (n=26) or RALP (n=25). Data was collected prospectively by the operating surgeon who measured the native, unfixed histology specimen directly after operation. The specimens were fixed in 10% Formaldehyde Solution BP and sent to the pathology laboratory where after sufficient fixation period was re-weighed. Results Overall mean age 64.78 years, TURP mean age 68.31 years RALP mean age 61.12years. We found that the overall prostatic specimen (n=51) weight loss after fixation was a mean of 11.20% (3.78 grams) (p≤0.0001). Subgroup analysis of the native TURP chips mean weight was 16.15 grams and formalin treated mean weight was 14.00 grams (p≤0.0001). Therefore, TURP chips had a mean of 13.32 % (2.15 grams) weight loss during chemical fixation. RALP subgroup unfixed specimen mean weight was 52.08 grams and formalin treated mean weight was 42.60 grams (p≤0.0001), a 19.32 % (9.48grams) mean weight reduction. Conclusion It has not been known that prostatic chips and whole human radical prostatectomy specimen undergo a significant weight reduction. The practical significance of the accurate prostate weight in patient management may be limited, however, it is agreed that this should be recorded correctly, as data is potential interest for research purposes and vital for precise documentation. .

Addition of lidocaine to levobupivacaine reduces intrathecal block duration: randomized controlled trial / Adição de lidocaína à levobupivacaína reduz a duração do bloqueio intratecal: estudo clínico randômico / La adición de lidocaína a la levobupivacaína reduce la duración del bloqueo intratecal: estudio clínico aleatorizado

Background: The duration of the spinal block is a concern for anesthetists. Low dose intrathecal lidocaine has vasodilatory effects and increases the local anesthetic clearance from the intrathecal space. The aim was to investigate whether this effect of lidocaine can be used to increase the resolution of levobupivacaine spinal anesthesia. Method: After obtaining ethical approval and informed patient consent, 40 patients underwent transurethral prostate resection were studied. Patients were randomized into two groups and patients received either levobupivacaine 6.75 mg + 0.3 mL 2% lidocaine (Group L) or levobupivacaine 6.75 mg + saline (Group C). The main outcome measures were the difference between groups regarding the duration of the spinal block and PACU stay. Secondary outcome measures were the difference between groups in onset and resolution of the spinal block, adverse events and treatments were also investigated. Results: Spinal block resolved faster in Group L than Group C; 162.43 ± 39.4 min vs 219.73 ± 37.3 min (p = 0.000). PACU time was shorter in Group L (109 ± 49.9 min in Group L vs 148 ± 56.8 min in Group C) (p = 0.036). There was no difference between groups with respect to the incidence of adverse events and treatments. Groups were also similar regarding complications. PDPH and TNS were not observed in any group. Conclusion: Addition of low dose lidocaine to hyperbaric levobupivacaine reduces the duration of the intrathecal block provided by hyperbaric levobupivacaine. This technique can be used to reduce the spinal block duration for relatively short procedures like TUR-P. .

Bipolar transurethral vaporization: a superior procedure in benign prostatic hyperplasia: a prospective randomized comparison with bipolar TURP

Objective To compare the outcomes of bipolar transurethral vaporization of the prostate (TUVP) with bipolar transurethral resection of the prostate (TURP). Materials and Methods In a prospective randomized trial, 88 patients with moderate to severe lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH) underwent bipolar TUVP (N = 39) or bipolar TURP (N = 49) from October 2010 to November 2011. The inclusion criteria were age > 50 years, prostate volume of 30-80mL, serum PSA < 4ng/mL, IPSS ≥ 20, Qmax ≤ 10mL/s and failed medical therapy. The perioperative and postoperative outcomes were evaluated and the IPSS and Qmax were assessed preoperatively and 3 months after procedure in all cases. Results Both groups were similar in patient age, prostate volume, preoperative IPSS and Qmax. The TUVP group had significantly lower mean values of operative time, hospital stay, catheterization period, irrigation fluid volume and serum hemoglobin, creatinine, sodium and potassium changes compared with TURP group. No significant differences were seen between two groups regarding complications (TUVP = 10.3%; TURP = 12.2%) and modified Clavien classification of complications. No TUR syndrome, obturator reflex or epididymitis occurred in both groups. Re-hospitalization and transfusion due to clot retention (N = 2) and urethral stricture (N = 1) were reported only in the TURP group. Three patients experienced urinary retention after catheter removal in the TUVP group. Two patients were re-catheterized temporarily and one patient required repeat bipolar TUVP. Three months after surgery, two groups had significant improvement in IPSS and Qmax. But the TUVP group had significantly lower IPSS and higher Qmax than TURP group. Conclusions Bipolar TUVP is a safe, effective and low cost procedure among minimally invasive surgeries of BPH. Compared with bipolar TURP, the bipolar TUVP had similar complications, better ...

Comparação de levobupivacaína em raquianestesia contínua ou com dose única para cirurgia de ressecção transuretral de próstata / The comparison of levobupivacaine in continuous or single dose spinal anesthesia for transurethral resection of prostate surgery / Comparación de la levobupivacaína en raquianestesia continua ocon dosis única para cirugía de resección transuretral de próstata

Justificativa e objetivo: comparar a eficácia de levobupivacaína na indução de raquianestesia contínua (RAC) versus dose única (Radu) em pacientes programados para ressecção transuretral de próstata (RTUP). Métodos: foram incluídos no estudo 50 pacientes, ≥ 60 anos, ASA I-II ou III. Levobupivacaína a 0,5% (12,5 mg) foi administrada por via intratecal no grupo Radu. No grupo RAC, levobupivacaína a 0,25% (2 mL) foi inicialmente administrada através de cateter espinhal. Para o nível de bloqueio sensorial atingir o dermátomo T10, 1 mL adicional de levobupivacaína a 0,25% foi administrado através do cateter a cada 10 minutos. Os parâmetros hemodinâmicos e as características do bloqueio foram registrados. Amostras de sangue dos pacientes foram coletadas nos períodos pré- e pós-operatórios para determinar os níveis plasmáticos de cortisona e adrenalina. Resultados: a RAC proporcionou melhor estabilidade hemodinâmica em comparação com a Radu, particularmente aos 90 minutos após a administração intratecal. O aumento do nível de bloqueio sensorial foi rápido e o tempo para atingir a anestesia cirúrgica foi menor no grupo Radu. O desenvolvimento do bloqueio motor foi mais rápido no grupo Radu. No grupo RAC, um nível semelhante de anestesia foi obtido com o uso de uma dose mais baixa de levobupivacaína, que foi relacionada à recuperação mais rápida. Embora ambas as técnicas tenham sido eficazes na prevenção da resposta ao estresse cirúrgico, os níveis de cortisona no pós-operatório foram mais suprimidos no grupo Radu. Conclusão: a técnica RAC com levobupivacaína a 0,25% pode ser usada como um método de anestesia regional em pacientes idosos programados para RTUP. .

Background: The aim of the study is to compare the efficacy of levobupivacaine induced continuous spinal anesthesia (CSA) versus single dose spinal anesthesia (SDSA) in patients who are planned to undergo transurethral prostate resection. Methods: Sixty years or older, ASA I-II or III, 50 patients were included in the study. 12.5 mg 0.5% levobupivacaine were administered intrathecally in SDSA group. In CSA group, initially 2 mL of 0.25% levobupivacaine were administered through spinal catheter. In order to achieve sensory block level at T10 dermatome, additional 1 mL of 0.25% levobupivacaine were administered through the catheter in every 10 min. Hemodynamic parameters and block characteristics were recorded. Preoperative and postoperative blood samples of the patients were drawn to determine plasma cortisone and plasma epinephrine levels. Results: CSA technique provided better hemodynamic stability compared to SDSA technique particularly 90 min after intrathecal administration. The rise in sensory block level was rapid and the time to reach surgical anesthesia was shorter in SDSA group. Motor block developed faster in SDSA group. In CSA group, similar anesthesia level was achieved by using lower levobupivacaine dose and which was related to faster recovery. Although, both techniques were effective in preventing surgical stress respond, postoperative cortisone levels were suppressed more in SDSA group. Conclusion: CSA technique with 0.25% levobupivacaine can be used as a regional anesthesia method for elderly patients planned to have TUR-P operation. .

Las muestras de sangre de los pacientes fueron extraídas en los períodos pre y postoperatorios para determinar los niveles plasmáticos de cortisona y adrenalina. Resultados: la técnica RAC proporcionó una mejor estabilidad hemodinámica en comparación con la técnica RADU, particularmente a los 90 min después de la administración intratecal. El aumento del nivel de bloqueo sensorial fue rápido y el tiempo para alcanzar la anestesia quirúrgica fue menor en el grupo RADU. El desarrollo del bloqueo motor fue más rápido en el grupo RADU. En el grupo RAC, un nivel parecido de anestesia se obtuvo con una dosis más baja de levobupivacaína que fue relacionada con la recuperación más rápida. Aunque ambas técnicas hayan sido eficaces en la prevención de la respuesta al estrés quirúrgico, los niveles de cortisona en el postoperatorio fueron mejor suprimidos en el grupo RADU. .

Holmium Laser Enucleation of the Prostate is Effective in the Treatment of Symptomatic Benign Prostatic Hyperplasia of Any Size Including a Small Prostate

PURPOSE: Although transurethral resection of the prostate (TURP) is considered the standard surgical treatment for benign prostatic hyperplasia (BPH), Holmium laser enucleation of the prostate (HoLEP) is replacing TURP. We compared TURP with HoLEP with matching for prostate size. MATERIALS AND METHODS: We retrospectively reviewed the medical charts of patients who underwent TURP and HoLEP performed by one surgeon at our institute. All patients were categorized into 3 groups on the basis of prostate size (group 1, 80 g), and 45 patients were selected for each method. RESULTS: No major intraoperative complications were encountered. The mean resected tissue weight was 6.3, 18.3, and 28.0 g for groups 1, 2, and 3, respectively, for TURP and 8.7, 25.0, and 39.8 g, respectively, for HoLEP. The mean operation time was 51.8, 89.3, and 101.9 minutes for TURP and 83.6, 122.8, and 131.2 minutes for HoLEP in groups 1, 2, and 3, respectively. HoLEP had better resection efficacy than TURP for any size prostate, but there was no statistical difference between the methods. Both methods resulted in an immediate and significant improvement of International Prostate Symptom Score, peak urinary flow rates, and postvoid residual urine volume. CONCLUSIONS: HoLEP is effective for BPH treatment, regardless of prostate size, even in a small prostate. The perioperative morbidity of HoLEP is also comparable to that of TURP.

Clinical Experiences of Incidental Prostate Cancer after Transurethral Resection of Prostate (TURP) According to Initial Treatment: A Study of a Korean High Volume Center

PURPOSE: These are the clinical experiences of Korean incidental prostate cancer patients detected by transurethral resection of the prostate according to initial treatment: active surveillance (AS), radical prostatectomy (RP) and hormone therapy (HT). MATERIALS AND METHODS: We retrospectively reviewed the records of 156 incidental prostate cancer patients between 2001 and 2012. The clinicopathologic outcomes were reviewed and follow-up results were obtained. RESULTS: Among 156 patients, 97 (62.2%) had T1a and 59 (37.8%) had T1b. Forty-six (29.5%) received AS, 67 (42.9%) underwent RP, 34 (21.8%) received HT, 4 (2.6%) received radiotherapy, and 5 (3.2%) chose watchful waiting. Of 46 patients on AS, prostate-specific antigen (PSA) progression occurred in 12 (26.1%) patients. Among them, 3 patients refused treatment despite PSA progression. Five patients, who underwent RP as an intervention, all had organ-confined Gleason score < or =6 disease. In 67 patients who underwent RP, 50 (74.6%) patients had insignificant prostate cancer and 8 (11.9%) patients showed unfavorable features. During follow-up, biochemical recurrence occurred in 2 patients. Among 34 patients who received HT, 3 (8.8%) patients had PSA progression. Among 156 patients, 6 patients died due to other causes during follow-up. There were no patients who died due to prostate cancer. CONCLUSION: The clinical outcomes of incidental prostate cancer were satisfactory regardless of the initial treatment. However, according to recent researches and guidelines, immediate definite therapy should be avoided without a careful assessment. We also believe that improved clinical staging is needed for these patients.

Standard surgical treatment for benign prostatic hyperplasia is safe for patients over 75 years: analysis of 100 cases from a high-volume urologic center

OBJECTIVES: In this study, we aimed to determine the complications of standard surgical treatments among patients over 75 years in a high-volume urologic center. METHODS: We analyzed 100 consecutive patients older than 75 years who had undergone transurethral prostatic resection of the prostate or open prostatectomy for treatment of benign prostatic hyperplasia from January 2008 to March 2010. We analyzed patient age, prostate volume, prostate-specific antigen level, international prostatic symptom score, quality of life score, urinary retention, co-morbidities, surgical technique and satisfaction with treatment. RESULTS: Median age was 79 years. Forty-eight patients had undergone transurethral prostatic resection of the prostate, and 52 had undergone open prostatectomy. The median International Prostatic Symptom Score was 20, the median prostate volume was 83 g, 51% were using an indwelling bladder catheter, and the median prostatespecific antigen level was 5.0 ng/ml. The most common comorbidities were hypertension, diabetes and coronary disease. After a median follow-up period of 17 months, most patients were satisfied. Complications were present in 20% of cases. The most common urological complication was urethral stenosis, followed by bladder neck sclerosis, urinary fistula, late macroscopic hematuria and persistent urinary incontinence. The most common clinical complication was myocardial infarction, followed by acute renal failure requiring dialysis. Incidental carcinoma of the prostate was present in 6% of cases. One case had urothelial bladder cancer. CONCLUSIONS: Standard surgical treatments for benign prostatic hyperplasia are safe and satisfactory among the elderly. Complications are infrequent, and urethral stenosis is the most common. No clinical variable is associated with the occurrence of complications.

Perioperative platelet inhibition in transurethral interventions: TURP/TURB

PURPOSE: To determine whether transurethral surgery under platelet inhibition is a feasible procedure. Before transurethral resection of prostate (TURP) or bladder tumours (TURB), the administration of platelet-inhibiting medication is often interrupted due to possible bleeding complications. We studied the performance of TURP and TURB under the current recommendations of the American College of Chest Physicians (ACCP) on perioperative platelet inhibition. MATERIALS AND METHODS: Patients assigned for transurethral intervention were preoperatively divided into the following risk groups: low, medium and high cardio- or cerebrovascular risk. In patients with a low-risk profile, acetylsalicylic acid (ASA) was discontinued. Patients of the medium risk group continued taking 100 mg of ASA. Patients of the high-risk group receiving dual platelet inhibition (ASA + clopidogrel) were not treated operatively. In total 346 patients from the low and medium risk groups underwent transurethral intervention. RESULTS: Forty-two out of 198 TURP were performed under 100 mg of ASA. Without ASA, a significantly shorter length of stay and earlier removal of the transurethral catheter was documented. In the parameters postoperative haemorrhage and operative revision, no significant differences were observed. Thirty-two out of 148 TURB were performed under 100 mg of ASA. Regarding the length of stay, time until catheter removal, postoperative haemorrhage and operative revision, no significant differences were found under ASA. Only significantly longer continuous irrigation was documented under ASA. CONCLUSION: In the case of a verified indication for use of platelet inhibitors, it is possible to avoid discontinuation and the consequent increased risk of thromboembolic incidents in transurethral surgery is admissible.

Elective hemi transurethral resection of prostate: a safe and effective method of treating huge benign prostatic hyperplasia

To evaluate the safety and efficacy of elective hemi-resection of prostate in patients with huge gland, weighing more than 120 grams. Multicentric, analytical comparative study. Department of Urology, Karachi Medical and Dental College, Abbasi Shaheed Hospital and Dr. Ziauddin Hospital, Karachi, from August 2006 to July 2009. All benign cases were included in this study and divided into two groups. In group A, patients having huge prostate [> 120 grams] were placed and hemi TURP was performed. In group B, patients having 60 to 100 grams prostate were placed and conventional Blandy's TURP was performed. Results of both groups were compared in terms of duration of surgery, amount of tissue resected, operative bleeding, postoperative complications, duration of postoperative catheterization, re-admission and re-operations. Effectiveness of procedure was assessed by a simple questionnaire filled by the patients at first month, first year and second year. Patients satisfaction in terms of their ability to void, control urination, frequency, urgency, urge incontinence, haematuria, recurrent UTI, re-admission and re-operations were also assessed. Fisher exact test was applied to compare the safety and efficacy of variables. In group A and B, average age range was 72 and 69 years, average weight of prostate was 148 and 70 grams, average duration of surgery was 102 and 50 minutes respectively. Average weight of resected tissue was 84 and 54 grams and haemoglobin loss was two grams and one gram respectively. Total hospital stay was 5 and 4 days. Total duration of indwelling Foley's catheter [postoperative] was 5 days and 2 days. Patient satisfaction in term of urine flow, urinary control, improvement in frequency and nocturia were comparable in both groups. UTI and re-admission was more in hemi-resection group. At the end of 2 years follow-up, there is no statistical difference between the safety and efficacy of two methods of treatment. In selected population, elective hemi TURP for huge obstructed prostate is a safe treatment. It's safety and short terms efficacy is comparable with the results of conventional TURP
