Perioperative Outcomes of Transurethral Resection, Open Prostatectomy, and Laser Therapy in the Surgical Treatment of Benign Prostatic Obstruction: A "Real-World" Data Analysis from the URO-Cert Prostate Centers.

INTRODUCTION: The aim of the study is to compare length of hospital stay, transfusion rates, and re-intervention rates during hospitalization for transurethral resection of the prostate (TUR-P), open prostatectomy (OP), and laser therapy (LT) for surgical treatment of benign prostatic obstruction (BPO). METHODS: URO-Cert is an organization, in which clinical data of prostatic diseases from 2 university, 19 public, and 3 private hospitals and 270 office-based urologists are collected in order to document treatment quality. Data on diagnostics, therapy, and course of disease are recorded web based. The analysis includes datasets from 2005 to 2017. RESULTS: Of 10,420 patients, 8,389 were treated with TUR-P, 1,334 with OP, and 697 with LT. Median length of hospital stay was 6 days (IQR: 4-7) for TUR-P, 9 days (IQR: 7-11) for OP, and 5 days (IQR: 4-6) for LT (p < 0.001). Risk for a hospital stay ≥7 days was higher for OP versus TUR-P (OR: 7.25; 95% CI = 6.27-8.36; p < 0.001) and LT (OR: 17.89; 95% CI = 14.12-22.65; p < 0.001) and higher for TUR-P versus LT (OR: 2.47; 95% CI = 2.03-3.01; p < 0.001). OP had a significantly higher risk for transfusions than TUR-P (OR: 2.44; 95% CI = 1.74-3.41; p < 0.001) and LT (OR: 3.32; 95% CI = 1.56-7.01; p < 0.001). Transfusion rates were not significantly different between TUR-P and LT (OR: 1.36; 95% CI = 0.66-2.79; p = 0.51). Risk of re-intervention was not different between all 3 approaches. CONCLUSION: OP was associated with higher transfusion rates and longer hospital stay than TUR-P and LT. Risk of transfusion was not different between TUR-P and LT, but TUR-P was inferior to LT concerning length of hospital stay. Re-intervention rates during hospitalization did not differ between the groups.

Detection of recurrent prostate cancer lesions before salvage lymphadenectomy is more accurate with (68)Ga-PSMA-HBED-CC than with (18)F-Fluoroethylcholine PET/CT.

AIM: [(68)Ga]PSMA-HBED-CC ((68)Ga-PSMA) is a novel and promising tracer for highly sensitive combined integrated positron emission tomography and X-ray computed tomography (PET/CT) diagnosis of recurrent prostate cancer (PCA). Our aim was to assess the sensitivity, specificity, positive and negative predictive value (PPV/NPV), and accuracy per lesion, as well as the positive predictive value per patient of (68)Ga-PSMA PET/CT using post-lymphadenectomy histology as a standard, and to compare these values to those obtained in a patient collective scanned using (18)F-Fluoroethylcholine ((18)FEC) PET/CT. METHODS: Thirty eight patients had (18)FEC and 28 patients had (68)Ga-PSMA. We performed a pelvic and/or retroperitoneal lymphadenectomy, if necessary supplemented by resection of locally recurrent lesions in accordance with imaging results. RESULTS: In 30/38 (18)FEC and 23/28 (68)Ga-PSMA patients ≥1 focus of PCA was identified in postsurgical histology, leading to a per-patient PPV of 78.9 % for (18)FEC and 82.1 % for (68)Ga-PSMA. In (18)FEC and (68)Ga-PSMA patients, a total of 378 and 308 lymph nodes and local lesions were removed, respectively. For (18)FEC and (68)for Ga-PSMA, the respective sensitivity (95 % confidence interval) was 71.2 % (64.5-79.6 %) and 86.9 % (75.8-94.2 %), specificity was 86.9 % (82.3-90.6 % ) and 93.1 % (89.2-95.9 %), PPV was 67.3 % (57.7-75.9 %) and 75.7 % (64.0-98.5 %), NPV was 88.8 % (84.4-92.3 %) and 96.6 % (93.5-98.5 %), and accuracy was 82.5 % (78.3-86.8 %) and 91.9 % (88.7 %-95.1 %). CONCLUSION: In the present series Ga-PSMA PET/CT shows a better performance than FEC PET/CT with a significantly higher NPV and accuracy for the detection of locoregional recurrent and/or metastatic lesions prior to salvage lymphadenectomy.

Surgical, oncologic, and short-term functional outcomes in patients undergoing robot-assisted prostatectomy after previous transurethral resection of the prostate.

PURPOSE: The objective of this study was to assess the surgical, oncologic, and short-term functional outcomes of patients with a history of transurethral resection of the prostate (TURP) who underwent robot-assisted laparoscopic prostatectomy (RALP). PATIENTS AND METHODS: The records of 2000 men who underwent RALP from February 2006 to April 2010 were retrospectively reviewed. A total of 80 men had undergone TURP before RALP. A match-paired analysis was performed using our database to identify 80 additional men without a history of TURP with equivalent clinicopathologic characteristics to serve as a control group (non-TURP group). The parameters compared included patient preoperative clinicopathologic characteristics, intraopeoperative characteristics, postoperative oncologic characteristics, minor and major postoperative complications, continence, and potency. RESULTS: The mean time between TURP and RALP was 3.6 months (3-6 months). Regarding preoperative characteristics, a statistical difference was only observed regarding preoperative patient potency in the TURP vs non-TURP group. Regarding intraopeoperative characteristics, a statistical difference was observed regarding the need for bladder neck reconstruction and skin-to-skin operative time. Regarding postoperative pathologic characteristics, the positive surgical margin rate was not significant when the two groups were compared. The continence and potency rates in 12 months were similar (87.5%/91.25%) and (70.3%/86.5%) for both patient cohorts. CONCLUSION: Although the procedure is technically more demanding, exhibits a prolonged operative time and time interval before continence and potency returns, it can be safely performed without compromising functional results as well as the radical nature of cancer surgery.
