RESUMO

PURPOSE: We reported preliminary outcomes of high-intensity focused ultrasound (HIFU) [Sonablate®] in the combination of transurethral resection of the prostate for localized prostate cancer in Taiwan. METHODS: Seventy-seven patients using Sonablate® HIFU for localized prostate cancer were enrolled in this study from April 2021 to December 2022. Prostate-specific antigen biochemical recurrence, International Index of Erectile Function (IIEF)-5 scores, International Prostate Symptom Score (IPSS), quality of life (QoL) scores, and postoperative complications were recorded during follow-up. RESULTS: Overall, 19.5% of patients were low-risk, 36.4% were intermediate-risk, and 44.1% were high-risk according to the D'Amico risk classification. The median follow-up was 12.09 ± 5.85 months, and the biochemical-free survival rates for the low-, intermediate-, and high-risk groups were 100% (15/15), 96.4% (27/28), and 79.4% (27/34), respectively. Four patients (5.2%) received salvage radiotherapy and all maintained biochemical-free survival. The mean IPSS and QoL scores before versus after HIFU were 10.4 versus 6.8 (p = 0.003) and 3.2 versus 3.0 (p = 0.096), respectively. There was no statistically significant change in preoperative and postoperative IIEF scores (20.6 vs. 19; p = 0.062) in patients who had an IIEF score of >15 at baseline and received nerve-sparing procedures (subtotal ablation). CONCLUSIONS: The results of Sonablate® HIFU in Taiwan indicated adequate short-term cancer control, excellent potency, and continence preservation. HIFU can achieve improvement of IPSS with low complication rates.

RESUMO

BACKGROUND: To determine the efficacy and safety of a periprostatic nerve block combined with perineum subcutaneous anaesthesia and intrarectal lidocaine gel for transrectal ultrasound-guided transperineal prostate biopsy (TPBx) through a prospective randomised controlled trial. METHODS: In total, 216 patients from May 2018 to November 2018 were randomly assigned to the experimental group and the control group at a ratio of 1:1. The experimental group received a periprostatic nerve block combined with subcutaneous perineal anaesthesia and intrarectal lidocaine gel. The control group received total intravenous anaesthesia. A visual analogue scale (VAS) score (0-10) was used to evaluate pain at different stages. The operative time, duration of hospitalisation, intraoperative vital signs, perioperative complications and clinicopathological features were recorded. RESULTS: The overall detection rate of prostate cancer was 40.74%, and the median Gleason score was 8 for all patients diagnosed with prostate cancer. No significant differences in terms of detection rates, Gleason scores and ISUP/WHO Grade Groups were found between the two groups (P > 0.05). The experimental group had no pain or just met the criteria for mild pain during the biopsy, which was significantly alleviated after the biopsy, and had a shorter operation time compared with that of the control group (P < 0.05). Compared with the control group, the experimental group had more stable haemodynamics and respiratory status and fewer surgical complications (P < 0.05). CONCLUSIONS: In multiple aspects, a periprostatic nerve block combined with subcutaneous perineal anaesthesia and intrarectal lidocaine gel is a safer and more efficient approach to local anaesthesia for TPBx that can almost replace total intravenous anaesthesia and is worthwhile applying in the clinical setting.

RESUMO

OBJECTIVE: To study the feasibility of transvesical prostate resection and its effect on urethral stricture. MATERIALS AND METHODS: We included 99 patients with symptomatic bladder outlet obstruction who underwent transvesical resection of prostate (TVRP; n = 48) and transurethral (TURP; n = 51) prostatectomy. We examined all the patients by means of digital rectal examination, transrectal ultrasound, and evaluated them by international prostate symptom score, quality of life score, uroflowmetric assessment and PSA level, and established definitive diagnosis. We followed up the patients in first month, third month, and the first year of the operation and monitored once a year in the following years. RESULTS: In this study, totally 99 symptomatic bladder outlet obstruction patients were included (TVRP = 48 and TURP = 51). Mean age of the patients were 66.5 ± 8.2vs 68 ± 9.8years for our patients with TVRP and TURP, respectively. Two groups displayed similar values in terms of improvements in the Qmax and PVR, and there were no statistically significant differences in between. We obtained similar values for resection time and weight of resected prostate tissue in both groups. Urethral stricture was not observed in TVRP group. In TURP group however, stricture was observed in 4 (7.8%) patients in bulbar urethra in sixth month at average. And there was also a concomitant urethral meatal stricture in one of these patients. When the 2 groups were compared, the rate of urethral stricture was statistically significantly higher in the TURP group (P = .001). CONCLUSION: Resection of prostate without using urethra significantly reduces the incidence of urethral stricture due to mucosal damage.

RESUMO

AIMS AND OBJECTIVES: To assess the effects of three different bowel preparation methods on the incidence of infectious complications in patients who underwent transrectal ultrasonography-guided prostate biopsy. BACKGROUND: The standard bowel preparation protocol for prostate biopsy has not been established. DESIGN: A retrospective study in a single centre. METHODS: From January 2013-December 2015, the clinical records of 1,130 patients who underwent prostate biopsy were, respectively, reviewed. All the patients received metronidazole prophylaxis before biopsy. The patients were divided into three groups according to the bowel preparation methods: patients in Group A (n = 402) received only soapy enema; patients in Group B (n = 413) received polyethylene glycol; while patients in Group C (n = 315) received polyethylene glycol plus povidone-iodine enema. Infectious complications were classified as fever (>37.5°C), urinary tract infection and sepsis. The postoperative adverse events were also observed. RESULTS: The overall postbiopsy infectious complications were observed in 48 (4.25%) patients of all the cases, including 23 (5.72%) cases in Group A, 20 (4.84%) cases in Group B and five patients (1.59%) in Group C. There was significant difference among the groups (p = .018). In detail, these infectious complications included 22 (1.95%) cases of fever and 26 (2.30%) cases of urinary tract infection. No sepsis was observed among the total patients. The incidence of adverse events was 14.43% (58/402) occurred in Group A, 25.91% (107/413) in Group B and 26.67% (84/315) in Group C. The difference was statistically significant. CONCLUSIONS: Our study confirmed that combined preparation regimens of polyethylene glycol with povidone-iodine enema could significantly reduce the postbiopsy infection rate. Conventional soapy enema is associated with less adverse events. RELEVANCE TO CLINICAL PRACTICE: Findings of this study provide useful evidence-based information for healthcare professionals. The application of combined preparation regimens of polyethylene glycol with povidone-iodine enema resulted in better improvement in the prevention of postbiopsy infection.

RESUMO

Over the past 25 years, the average life expectancy for men has increased almost 4 years, and the age of prostate cancer detection has decreased an average of 10 years with diagnosis increasingly made at early-stage disease where curative therapy is possible. These changing trends in the age and extent of malignancy at diagnosis have revealed limitations in conventional curative therapies for prostate cancer, including a significant risk of aggressive cancer recurrence, and the risk of long-term genitourinary morbidity and its detrimental impact on patient's quality of life (QOL). Greater awareness of the shortcomings in radical prostatectomy, external radiotherapy, and brachytherapy has prompted the search for alternative curative therapies that offer comparable rates of cancer control and less treatment-related morbidity to better preserve QOL. High-intensity focused ultrasound (HIFU) possesses characteristics that make it an attractive curative therapy option. HIFU is a noninvasive approach that uses precisely delivered ultrasound energy to achieve tumor cell necrosis without radiation or surgical excision. In current urologic oncology, HIFU is used clinically in the treatment of prostate cancer and is under experimental investigation for therapeutic use in multiple malignancies. Clinical research on HIFU therapy for localized prostate cancer began in the 1990s, and there have now been ∼65,000 prostate cancer patients treated with HIFU, predominantly with the Ablatherm (EDAP TMS, Lyon, France) device. Neoadjuvant transurethral resection of the prostate has been combined with HIFU since 2000 to reduce prostate size, facilitate tissue destruction, and to minimize side effects. Advances in imaging technologies are expected to further improve the already superior efficacy and morbidity outcomes, and ongoing investigation of HIFU as a focal therapy in salvage and palliative indications is serving to expand the role of HIFU as a highly versatile noninvasive therapy for prostate cancer.

RESUMO

AIM: To evaluate whether a combination method involving the transrectal (TR) and transperineal (TP) approach can increase the cancer detection rate relative to the TR approach regarding repeat prostate biopsy. PATIENTS AND METHODS: One thousand and nineteen patients underwent initial prostate biopsies and 298 repeat prostate biopsies. All initial biopsies were conducted transrectally. Of the repeat biopsies, 179 (60.1%) were performed using the combined transrectal and transperineal (TR+TP) approach; 113 (37.9%) were carried out transrectally. All biopsies were performed under ultrasound guidance using a 16-gauge core biopsy needle; 651 were diagnosed as prostate cancer; 224 patients underwent radical prostatectomies (RPs). We evaluated the cancer detection rates between the biopsy methods in the repeat biopsy cohort and compared the clinical and pathological features of the RP specimens between the initial and repeat biopsy groups. RESULTS: A median of 12 and 20 cores were obtained in the initial and repeat biopsy patients, respectively. Cancer detection rates regarding biopsies 1, 2, 3, 4 and 5 were 49.2% (551/1,119), 34.7% (75/216), 33.3% (20/60), 26.7% (4/15) and 14.3% (1/7), respectively. There were no significant differences between the TR and the TR+TP approach (32.7% vs. 33.5%). RP specimens diagnosed using repeat biopsies showed more anterior dominant tumors relative to those diagnosed using the initial biopsies (59.5% vs. 35.9%; p<0.001). CONCLUSION: The TR+TP combination approach could not increase cancer detection rates relative to the TR approach in the repeat biopsy cohort. However, 16-gauge needle biopsy demonstrated acceptable cancer detection rates in the comparatively small number of biopsy cores.

RESUMO

Contexto: Los tratamientos radicales o de seguimiento activo son alternativas en el manejo del cáncer de próstata localizado, ambos no exentos de riesgos y efectos secundarios. El objetivo de este trabajo es analizar las diferentes posibilidades de la terapia focal en sus diferentes opciones para tratar el cáncer de próstata localizado. Adquisición de evidencia: Realizamos una revisión en Medline de las diferentes posibilidades de tratamiento focal desde el punto de vista técnico, desarrolladas en la actualidad con atención a los estudios prospectivos aleatorizados, así como las formas de seguimiento y evolución de resultados. Síntesis de evidencia: Diferentes técnicas en este momento están disponibles para realizar terapia focal, básicamente aquellas mínimamente invasivas -terapia vascular fotodinámica (TVF), crioterapia, braquiterapia, ultrasonido focalizado de alta intensidad (HIFU), láser intersticial- que permiten acceso directo y dirigido a la glándula. Los resultados preliminares de los estudios actuales demuestran una buena aceptabilidad de las técnicas con escasos efectos secundarios y buenos resultados oncológicos. La biopsia junto con la resonancia magnética nuclear (RMN) son las guías de seguimiento en estos pacientes, siendo el papel del antígeno prostático específico (PSA) menos definido. Conclusiones: La terapia focal es en la actualidad una alternativa con técnicas disponibles para una buena ejecución. Los datos actuales apuntan a una escasa morbilidad y buenos resultados oncológicos que hacen de la terapia focal una posible alternativa de tratamiento en los tumores localizados, a la espera de los resultados de más estudios aleatorizados


Context: The great controversy surrounding the treatment of localized prostate cancer is related with its possibilities of radical treatment or active surveillance. The objective of this paper is to analyze the rationale selection among current focal therapy modalities regarding tumor and patient selection. Evidence acquisition: Current articles about advantages and disadvantages on the treatment of localized prostate cancer as well as information about focal therapy regarding tumor selection, characteristics and indications cited in MEDLINE search were reviewed. Summary of evidence: Focal therapy standardized criteria must be: low risk tumors, PSA < 10-15, Gleason score ≤ 6, and unilateral presentation all supported by image-guided biopsy and nuclear magnetic resonance (NMR). There are doubts about the suitability of focal therapy in cases of bilateralism or in those with Gleason score 3 + 4 or PSA > 15. Conclusions: Focal therapy is an alternative for localized prostate cancer treatment. However, some aspects of their diagnosis and selection criteria should be defined by prospective studies which should provide knowledge about the indication for focal therapy

RESUMO

The study was aimed to the assessment of the effectiveness of treatment for prostate cancer using high-intensity focused ultrasound on the basis of clinical, radiation, laboratory data, and results of morphometric and immunohistochemical study of postoperative prostate biopsies. 112 sessions of HIFU-ablation of the prostate in 112 patients with localized prostate cancer were performed. Average number of impulses of action--634 +/- 176, the average volume of tissue exposed--34.6 +/- 15.2 cm3 per 1 session. The operative time ranged from 90 to 165 min (mean 125 min). The postoperative hospital stay ranged from 7 to 14 days (average 10 +/- 0.8 days). Intraoperative complications during HIFU-ablation were not observed. The average level of prostate-specific antigen 1,5 months after surgery was 0.7 (0.12-3.67) ng/ml. Minimum level of prostate-specific antigen was reached 20 +/- 2 weeks after treatment, and the average level was 0.26 +/- 0.01 ng/ml. 6 months after, prostate volume decreased by an average of 49%; 10-12 months after intervention, prostate volume was 6.5 +/- 2.2 cm3. Morphological analysis after treatment included studies with standard and immunohistochemical staining using the following antibodies: PCNA, Bcl2, AMACR, E-cadherin, ANDR. Recurrence-free course was observed in 96 (85.8%) patients. Recurrences were detected in 16 (14.2%) patients, with biochemical progression in 11 (9.82%) patients. Local recurrence (morphologically confirmed) was diagnosed in 5 (4.46%) patients.

RESUMO

OBJETIVO: El atractivo del HIFU (High intensity focused ultradound) robotizado se basa ampliamente en la naturaleza no invasiva, extremadamente precisa de este tratamiento robótico de alta tecnología, así como su carácter limpio, sin radiación, quirúrgico y sin embargo sin sangrado. Hoy, en urología oncológica, el HIFU se utiliza clínicamente cómo una herramienta terapéutica para el tratamiento del cáncer de próstata. Su uso terapéutico en cáncer de riñón y mama se está investigando a nivel experimental.El tratamiento del cáncer de próstata localizado con HIFU transrectal ha sido investigado desde los años 90, y mientras tanto es una terapia utilizada activamente contra la enfermedad en muchos departamentos deurología en todo el mundo. Desde el 2000 el HIFU se utiliza principalmente en combinación con resección transuretral de próstata para reducir el tamaño de la glándula prostática, facilitar la destrucción efectiva del tejido y evitar los efectos secundarios. Las indicaciones paliativas y de salvación, así como el tratamiento focal del cáncer de próstata están siendo investigadas para extender el espectro de indicaciones del HIFU en el tratamiento no invasivo del cáncer de próstata(AU)

RESUMO

OBJECTIVES: To evaluate the long-term outcomes of transurethral resection of the prostate (TURP) immediately after high-intensity focused ultrasound (HIFU) treatment for prostate cancer (CaP). METHODS: The present retrospective study included 65 CaP patients who underwent HIFU alone and 64 patients who underwent TURP immediately after HIFU. HIFU treatment was carried out using a Sonablate-500 HIFU device (Focus Surgery, Indianapolis, IN, USA). International Prostate Symptom Score (IPSS) and the occurrence of urinary complications, such as urethral stricture during follow-up, were statistically compared between groups. RESULTS: Clinical stage tended to be lower for the HIFU+TURP group (P=0.0311), but none of the preoperative parameters differed significantly between groups. Both catheterization time (P<0.0001) and post-treatment IPSS (P<0.0001) at 6, 12, and 24months after treatment differed significantly between groups. Urethral strictures were noted in 16 (24.6%) of the HIFU-only patients and seven (10.9%) of the HIFU+TURP patients. Bladder neck contracture was noted in 11 (68.8%) of the patients with urethral stricture in the HIFU-only group, but in just two (28.6%) of the patients with urethral stricture in the HIFU+TURP group. Multiple logistic regression analyses showed that TURP resection volume (P=0.0118) was a strong factor for the prevention of urethral stricture. CONCLUSIONS: Our results suggest that combining HIFU with an immediately following TURP improves post-treatment urinary status without causing additional morbidity.

RESUMO

Imaging in cancer has moved in the last twenty years from morphological detection of diseases to characterization and categorization of different subtypes of tumors. Functional information, based on dynamic contrast-enhanced imaging of tissue perfusion and evaluation of water diffusion, tissue oxygenation, capillary permeability or lymphatic drainage, plays a major role in that field.The next coming steps will concern the differentiation of biological behaviour of tumors according to their phenotypes by identifying specific surface receptors or products of synthesis.These developments allowing an in vivo identification of the tumor biological singularities is a tremendous progress in the management of cancer at the step of diagnosis but, more importantly, to assess the most appropriated treatment to each tumor type. At the same time, minimally invasive methods of treatment of tumors have also developed, mainly in the field of thermotherapies. Ablation of tumors using radiofrequency is now used in clinics as a new standard within the liver and as a promising additional option in many other organs as kidney, lung and bone. High intensity focused ultrasound (HIFU) showed more restricted developments in clinics, mainly applied to prostatic cancer, because of many technical barriers. We believe that magnetic resonance (MR) imaging and MR-guided HIFU (MRgHIFU) have a great potential in that field due to the capacity of MR imaging to monitor temperature changes for an optimal heat deposition and for an optimal safety. This technique has already gained recognition for the treatment of uterine leiomyomas. But it has still to prove its efficacy in treatment of malignant tumors. This review will focus on some recent developments in molecular characterisation of tumors using MR imaging and in technical improvements necessary for accurate application of MRgHIFU in cancer.

RESUMO

PURPOSE: The aim of the present randomized study was to evaluate the efficacy of lidocaine gel compared with dimethylsulfoxide (DMSO) with lidocaine for transrectal ultrasonography (TRUS)-guided prostate biopsy in patients with anorectal pathologies. PATIENTS AND METHODS: Sixty-two patients were randomly divided into two equal groups. Group 1 was given 10 mL of 2% lidocaine gel intrarectally 10 minutes before the biopsy. Group 2 was given 10 mL of intrarectal 40% DMSO with an amount of lidocaine equal to that in the lidocaine gel 10 minutes before the procedure. The degree of pain was rated by patients using a 10-point visual analog scale. RESULTS: The pain scores for probe insertion were significantly lower for group 2 (3.15 +/- 1.41) than for group 1 (4.58 +/- 160) (P = 0.01). No significant differences were found between the pain scores of the two groups for biopsy-needle insertion (P = 0.62). CONCLUSIONS: Dimethylsulfoxide with lidocaine instilled into the rectum is a simple, safe, rapid-acting, and effective method of anesthesia delivery before TRUS-guided prostate biopsy in patients with anorectal pathologies.

Introducción y Objetivos: Estudio de eficacia en la prevención de complicaciones infecciosas tras biopsia transrectal de próstata. Revisión de las complicaciones infecciosas y microorganismo implicados. Material y métodos: Estudio prospectivo y aleatorizado en 153 pacientes en los que se realizaron 157 biopsias de próstata. El Grupo A (71 pacientes) recibieron tobramicina 100 mg una dosis intravenosa media hora antes de la biopsia y otra intramuscular a las 8 horas de la primera, y los del Grupo B (85 pacientes) recibieron el mismo esquema de tobramicina y añadiendo ciprofloxacino oral 500 mg media hora antes de la biopsia continuando luego con una dosis cada 12 horas durante tres días. Resultados: en el Grupo A se realizaron 71 biopsias y en el Grupo B 86. 50 pacientes (31,8%) presentaron hematuria, 20 (12,7%) fiebre, 15 (9,5%) hemospermia, 7 (4,4%) dolor perineal, uno (1,2%) orquiepididimitis y otro (1,2%) retención urinaria. De los pacientes con fiebre 15 pertenecen al grupo A y 5 al grupo B (p=0,004). Ingresaron por fiebre 15 (21,1%) pacientes del grupo A y 3 (3,5%) del grupo B (p=0,0006). En el 67% de los hemocultivos se aisló E. Coli. Conclusiones: La pauta profiláctica consistente en tobramicina más ciprofloxacino resultó ser más eficaz en la prevención de ingresos por fiebre post-biopsia que la tobramicina sola. La complicación más frecuente fue la hematuria. El microorganismo más frecuentemente fue E. Coli sensible, en nuestro hospital, a amoxicilina-clavulánico, tobramicina y cefalosporinas de tercera generación


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

RESUMO

AIM: This study was designed to compare the effectiveness of intrarectal lidocaine gel versus periprostatic lidocaine injection during transrectal ultrasound (TRUS)-guided prostate biopsy. METHODS: Ninety men undergoing transrectal prostate biopsy from July through December 2004 were randomized into three groups of 30 patients each. Before the biopsy, patients in Group 1 received 20 mL of 2% lidocaine gel intrarectally; patients in Group 2 received 5 mL (2.5 mL per side) of 2% lidocaine solution injected near the junction of the seminal vesicle with the base of the prostate (along the neurovascular bundles), and patients in Group 3 (control group) received 5 mL (2.5 mL per side) of normal saline injected along the neurovascular bundles. Pain level after the biopsy was assessed using a 10-point linear visual analog scale (VAS). Results were statistically compared by the Wilcoxon Rank Sum test. RESULTS: Patients in Group 2 had significantly lower VAS scores than those in Group 3 (3.6 +/- 2.1 vs 5.8 +/- 1.9, P < 0.0001), but those in Group 1 did not (5.5 +/- 2.7 vs 5.8 +/- 1.9, P = 0.67). Gross hematuria, rectal bleeding, and hemospermia occurred in 36 (40.0%), 6 (7%) and 5 (6%) patients. One patient had temporary vasovagal syncope. No patient reported febrile urinary tract infection or urinary retention. CONCLUSIONS: Periprostatic injection of local anaesthetic is a safe technique that significantly reduces pain during prostate biopsy, whereas intrarectal lidocaine injection did not reduce pain. This safe, simple technique should be applied in men undergoing TRUS-guided prostate biopsy to limit patient discomfort.

RESUMO

We report a 62 years old kidney transplant (KT) patient who was diagnosed of localized prostatic cancer (PC) after 6 years of the implant. Transrectal prostatic High Intensity Focused Ultrasound (HIFU) was applied. Results have been satisfactory, achieving pathologic and biochemical success. The discharge was completed at 24 hs, the morbidity was minimal. We have not found any reference in the literature on the appliance of HIFU in PC KT patients. We think that HIFU may represent a good alternative for these patients.

RESUMO

Presentamos el caso de un paciente de 62 años portador de un trasplante renal (TR) que fue diagnosticado a los 6 años del implante de adenocarcinoma prostático (CP) localizado. Tras evaluar las alternativas terapéuticas se optó por el Ultrasonido de Alta Intensidad (HIFU) por vía transrectal. El resultado ha sido satisfactorio, con ingreso de 24 horas, resolución histológica y bioquímica y mínima morbilidad. No hemos hallado en la literatura referencias a la utilización de HIFU en CP en la población de trasplantados renales. Creemos que puede representar una buena alternativa terapéutica

RESUMO

OBJECTIVES: To report on our 5-year results with transrectal high-intensity focused ultrasound (HIFU) in the treatment of localized prostate cancer. HIFU delivers high energy, causing rapid coagulation necrosis of tissue within the target area without damaging the surrounding tissue. METHODS: A total of 146 patients with biopsy-proven Stage T1-T2N0M0 prostate cancer have been treated using the Ablatherm device. All patients had a prostate-specific antigen (PSA) level of 15 ng/mL or less and a Gleason score of 7 or less (inclusion criteria). The mean follow-up was 22.5 months (range 4 to 62) and included PSA measurement and control sextant biopsies. RESULTS: The median PSA nadir 3 months after treatment was 0.07 ng/mL (range 0 to 5.67). The median PSA level after a follow-up of 22 months was 0.15 ng/mL (range 0 to 12.11), and 87% of the patients had a constant PSA level of less than 1 ng/mL; 93.4% of all patients had negative control biopsies. One rectourethral fistula was noted after a second HIFU treatment in a patient with a history of hemicolectomy and repetitive anal fistulas. Of all the patients, 12% underwent transurethral resection after HIFU because of obstruction, but no severe stress incontinence (grade 2 to 3) was observed. Erectile function was preserved in 47.3% of patients, and the International Prostate Symptom Score and Quality of Life Index did not change from before to after treatment. CONCLUSIONS: Our results demonstrated the efficacy and low-associated morbidity of HIFU. HIFU does not exclude other treatment options and is repeatable. HIFU seems to be a valid alternative treatment for patients who are not suitable for radical surgery.
