Comparison of computed tomography and magnetic resonance imaging in the assessment of complex renal cysts by using the Bosniak classification. / Comparación entre tomografía computarizada y resonancia magnética en la evaluación de quistes renales complejos empleando la clasificación de Bosniak.

INTRODUCTION AND OBJECTIVES: The Bosniak classification of cystic renal lesions was first published in 1986 based on computed tomography (CT). In the present study, we aimed to investigate the effect of magnetic resonance imaging (MRI) on Bosniak category compared with CT, and to determine how this effect changed the treatment modality in the evaluation of complex renal cysts. MATERIAL AND METHODS: Data of 144 patients were collected retrospectively. After exclusion criteria, 102 cystic renal lesions with a Bosniak category of at least IIF on CT or MRI between 2013 and 2016 were evaluated by 2abdominal radiologists. The demographic data, Bosniak category, interobserver agreement, and pathologic data of patients who underwent surgery were recorded. RESULTS: The coherence between MRI and CT was 75.5%. The Bosniak classification of 17 patients was upgraded with MRI, and the treatment modality changed in 10 patients, and they underwent surgery. The Bosniak category was downgraded from III to IIF in 6 patients out of 8 whose Bosniak category was downgraded with MRI and the treatment modality changed. Surgery was performed in one patient out of these 6 patients, and the pathology was reported as benign. Progression was detected in the follow-up at month 18 of 1 patient out of 5, and surgery was performed. The pathology was reported as renal cell carcinoma. The pathology result was reported as RCC in 35 (68.6%) patients out of 51 who underwent surgery. Progression was detected in 7 patients out of 51 who were followed up (13.7%), and the pathology results were reported as RCC. The majority of the malignant tumors were low stage and grade. CONCLUSIONS: MRI may be successfully used in the evaluation of renal cystic lesions. In particular, the challenging Bosniak IIF and all Bosniak III lesions must be evaluated using MRI before making the decision for surgery. The upgrading of Bosniak category with MRI is more possible compared with CT due to its high-contrast resolution, therefore further studies are required to identify whether it was the cause of overtreatment of Bosniak III lesions.

Acupuncture relieves symptoms in chronic prostatitis/chronic pelvic pain syndrome: a randomized, sham-controlled trial.

BACKGROUND: There are multiple approaches to the management of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS); and lately the data suggesting the ability of acupuncture treatment to decrease pain, positively impact quality of life and potentially modulate inflammation has suggested it as a potential therapeutic option for men with CP/CPPS. We conducted this study to determine whether acupuncture is really an effective therapeutic modality for CP/CPPS in terms of >50% decrease in total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score from baseline compared with sham. METHODS: One hundred patients with CP/CPPS (category III B) in an outpatient urology clinic were randomized to receive acupuncture at either seven acupoints bilaterally or sham points adjacent to these points. NIH-CPSI was completed by each patient before and 6, 8, 16, 24 weeks after the treatment. Mean values of total CPSI score and subscores after the treatment and on follow-up following the treatment were compared. RESULTS: Of the acupuncture participants, 92% were NIH-CPSI responders (>50% decrease in total NIH-CPSI score from baseline) compared with 48% of sham participants, 8 weeks after the end of the therapy. Both groups experienced significant decrease in CPSI subscores throughout the whole follow-up period; however, the decline remained significantly greater in the active acupuncture group as compared with the sham group. CONCLUSIONS: Our results show that the use of acupuncture in treatment of men with CP/CPPS symptoms resulted in a significant decrease in total NIH-CPSI scores.

Oncologic results, functional outcomes, and complication rates of robotic-assisted radical prostatectomy: multicenter experience in Turkey including 1,499 patients.

BACKGROUND: Robot-assisted radical prostatectomy (RARP) is a rising minimally invasive treatment of localized prostate cancer (PC). We present our multicenter experience of 1,499 consecutive cases with an analysis of complication rates, oncologic, and functional outcomes. PATIENTS AND METHODS: From March 2005 through December 2012, details of 1,499 patients were retrospectively analyzed. Transperitoneal approach using a da-Vinci robotic system was used to perform RARP. Perioperative characteristics and postoperative oncologic and functional outcomes are reported. RESULTS: The mean age was 61.3 years (37-77). Mean PSA level was 8.3 ng/ml. According to D'Amico classification, the percentage of patients with low-, intermediate-, and high-risk disease cases were 65.0, 30.1, and 4.8 %, respectively. Mean operative time was 181.9 min. Mean estimated blood loss was 225.4 cc (30-1,250). Positive surgical margin (PSM) was detected in 212 (14.1 %) patients. PSM rates in pT2, pT3, and pT4 stages were 6.1, 37.1, and 100 %, respectively. The overall complication rate due to modified Clavien classification was 6.1 %. Mean follow-up time was 26.7 months. Continence, potency, and biochemical recurrence rates were 88.7, 58.2, and 2.9 %, respectively. CONCLUSIONS: Our analyses including high-volume centers, which is the first largest series in Turkey, show that RARP is a safe procedure, has low PSM rates, high continence, and potency rates for the treatment of localized PC at experienced centers.

Oncologic results, functional outcomes, and complication rates of transperitoneal robotic assisted radical prostatectomy: single centre's experience.

BACKGROUND: We report the operative details and short term oncologic and functional outcome of the first 334 Robotic-assisted radical prostatectomy experiences for organ confined prostate cancer METHODS: From August 2009 to December 2012, details of 334 consecutive patients were retrospectively analyzed. The analyzed parameters included: preoperative, per-operative characteristics, postoperative minor and major complications, positive surgical margin continence, potency, and biochemical progression at the follow-up period. RESULTS: The classical extrafascial, interfascial, intrafascial and fascia sparing radical prostatectomy were performed in 31, 41, 200, and 62 cases, respectively. The mean operation time was 213.8±90.1minutes, and the mean estimated blood loss was 116.1±58.9cc during operation. A nerve-sparing procedure was performed bilaterally in 198 (59.3%) cases and unilaterally in 126 (37.7%) cases. The catheter was removed on postoperative day 9, 1±1.9. Surgical margin was positive in 36 (10.7%) patients. The overall, pT2, pT3a and pT3b PSM rates were 8 (2.4%), 12 (3.6%), 16 (4.8%) respectively and PSM and BCR rates were not statistically different among four approach (P>.05). At the follow-up period, the continence rates were 74.4%, 80.4%, 80.5%, and 96.7% (P<.001), and previously potent patients' potency rates were 64.3%, 66.6%, 68.1%, and 74.5% (P>.05), in classic extrafascial, interfascial, intrafascial, and fascia sparing intrafascial prostatectomy, respectively. CONCLUSION: RARP is a safe and feasible technique in treatment of localized prostate cancer. Fascia sparing approach has better continence rate. This results need to be supported by new prospective, randomized studies.

Hemorragia de la pared abdominal después de prostatectomía radical asistida por robot: ¿es una complicación de la cirugía robótica? / Abdominal Wall Haemorrhage After Robotic-Assisted Radical Prostatectomy: Is it a Complication of Robotic Surgery?

Objetivo: La prostatectomía radical asistida por robot (PRAR) es el tratamiento quirúrgico mínimamente invasivo para los pacientes con cáncer de próstata localizado. Se han notificado complicaciones perioperatorias o postoperatorias después de PRAR en algunos estudios, y el sangrado postoperatorio severo después de PRAR es poco común, pero puede ser que la inestabilidad hemodinámica requiera exploración quirúrgica abierta y se asocie con una morbilidad considerable. Informamos de casos de sangrado postoperatorio, que es una especie de complicación asociada con la cirugía robótica, y la necesidad de transfusión masiva después de PRAR. Pacientes y métodos: Desde agosto de 2009 hasta mayo de 2012 317 pacientes consecutivos sometidos a PRAR en nuestra institución fueron analizados. Los pacientes con hemorragia postoperatoria grave, que causó inestabilidad hemodinámica después de la cirugía, fueron estudiados. Resultados: Un total de 5 de entre 317 (1,6%) pacientes tuvieron hemorragia que requería transfusión postoperatoria. En estos casos la media de tiempo operatorio fue de 114 min. La media de pérdida estimada de sangre fue de 110 ml durante la operación. En estos pacientes los niveles de hematocrito (Hct) gradualmente disminuyeron después de la cirugía, y se detectó equimosis en las paredes laterales y posteriores del abdomen en el segundo día. El Hct preoperatorio medio fue de 44,3% y el Hct medio más bajo fue de 23,1%. Todos los pacientes fueron tratados exitosamente sin exploración quirúrgica. Conclusiones: La prostatectomía radical robótica ha demostrado ser un tratamiento quirúrgico seguro con baja morbilidad. Sin embargo, el sangrado postoperatorio puede llegar a problemas serios. Este es el primer estudio para explicar la hemorragia asociada con el posible riesgo de la cirugía robótica (AU)

Objective: Robotic-assisted radical prostatectomy (RARP) is the minimally invasive surgical treatment for patients with localized prostate cancer. Perioperative or postoperative complications following RARP have been reported in some studies and severe postoperative bleeding after RARP is rare, but haemodynamic instability may necessitate open surgical exploration and be associated with considerable morbidity. We reported postoperative bleeding cases, which is a kind of complication associated with robotic surgery and requiring massive transfusion after RARP. Patients and methods: From August 2009 to May 2012, 317 consecutive patients who underwent RARP performed at our institution were analyzed. Patients with serious postoperative bleeding that caused haemodynamic instability after surgery were enrolled. Results: A total of 5 among 317 (1.6%) patients had bleeding requiring postoperative transfusion. In these cases, mean operative time was 114 min. The mean estimated blood loss was 110 ml during operation. In these patients, hematocrit (Hct) levels gradually fell after surgery and ecchymosis was detected on the side and posterior walls of the abdomen on the second day. The mean preoperative Hct was 44.3% and mean lowest Hct was 23.1%. All patients were successfully treated without surgical exploration. Conclusions: Robotic radical prostatectomy has proven to be a safe surgical treatment with low morbidity. However, postoperative bleeding can reach serious problems. This is the first study to explain haemorrhage, associated with possible risk of robotic surgery (AU)
