“…When the whole adenoma was almost dissected from the capsule, then they were resected into smaller prostatic chips. At the end of both procedures, a 22Fr triplelumen catheter was inserted into the bladder and irrigation was initiated [20,21].…”

Objective. To assess the value of clinically relevant data for predicting the failure of removal of the urinary catheter within 48 hours after TUERP. Materials and Methods. We retrospectively analyzed the medical records of 357 patients who underwent TUERP between January 2015 and July 2018, all of whom stopped bladder irrigation and removed urinary catheter within 48 hours after the operation. According to whether the removal of the catheter was successful, the patients were classified into 2 groups: Group A was successful and group B was a failure. Univariate analysis was performed to determine the association between the failure of removal of the catheter and the patients’ preoperative clinical characteristics. Logistic regression analysis and receiver operating characteristic analysis (ROC) were conducted to establish the prediction model. Then the area under the curve (AUC) and the cut-off value were calculated. Results. 357 patients were divided into group A (n = 305, 85.4%) and group B (n = 52, 14.6%). The patients’ drug medication (P=0.006), history of acute urinary retention (AUR) (P≤0.001), smoke (P=0.045), IPSS (P≤0.001), IPP (P=0.006), PSA (P=0.047), residual urine volume (P≤0.001), QoL (P≤0.001), and TPV (P=0.043) were significantly different between the 2 groups. A predictive model using logistic regression was defined as follows: INDEX = 10.862–1.376 × (IPSS) − 1.185 × (QoL) − 1.062 × (drug medication) + 1.079 × (history of AUR) + 0.030 × (TPV) − 0.867 × (IPP) with area under the curve of 0.860 obtained from the ROC curve analysis. The predictive model had a cut-off value of 1.7725, and the sensitivity for predicting the failure of removal of the urethra was 74.1% and the specificity was 84.6%. Conclusion. This study demonstrated that IPSS, QoL, drug medication, history of AUR, TPV, and IPP are independent factors associated with the failure of removal of the urethral catheter within 48 hours after TUERP.

“…As shown in Table 2, patients who underwent bipolar enucleation showed comparable outcomes regardless of differences in surgical techniques and the devices (Abou‐Taleb et al, 2017; Autorino et al, 2009; Chiruvella et al, 2018; Giulianelli et al, 2019; Xu et al, 2018). Further investigations would be mandatory to show detailed differences according to different surgical techniques.…”

“…Thus, in clinical practice, bipolar enucleation of prostate includes both enucleation and morcellation procedures. Many researchers have evacuated enucleated tissues using ‘Mushroom technique’ without a morcellator (Abou‐Taleb et al, 2017; Chiruvella et al, 2018; Gu et al, 2018; Hirasawa et al, 2012). However, safety and efficacy of morcellation after bipolar enucleation have also been demonstrated in previous studies when the surgeons kept in mind some surgical principles (Hirasawa et al, 2012).…”

“…According to previous studies, 24 or 26 Fr resectoscopes are commonly used for the procedure. The range of energy settings used by previous researchers was 130 W to 280 W for cutting and 60 W to 110 W for coagulation (Abou‐Taleb, 2017; Chiruvella et al, 2018; Gu et al, 2018; Hirasawa et al, 2012; Neill, 2006; Xu, 2018).…”

“…To start enucleation of lateral lobes, proper surgical plain should be identified in order to prevent external sphincter injury and reduce the risk of bleeding (Chiruvella et al, 2018; Xu et al, 2018). Through above‐mentioned incisions on apex of prostate, separation between surgical capsule and lateral lobe of adenoma is performed laterally and upwardly (Figure 4e).…”

Bipolar enucleation of prostate (BipolEP) is a useful method for treatment of benign prostatic hyperplasia (BPH). Compared with conventional transurethral resection, the enucleation technique has several advantages. However, since the cost of laser equipment used for enucleation is relatively high, enucleation using bipolar devices has been attempted by many previous surgeons. We consider bipolar enucleation is an effective and safe procedure, and we would like to share our experience of equipment settings and procedures through this article. We will introduce the equipment and settings of BipolEP and then present the actual step-by-step procedures and surgical tips. First, circular incisions are made on bladder neck and mucosa at the level of verumontanum. Then, enucleation is performed in the order of median and lateral lobes as in laser enucleation. Haemostasis should be done throughout the procedure. After enucleation and haemostasis, prostatic tissue is evacuated by morcellator. Currently, there are several types of electrode and morcellator systems. In our experience, BipolEP has a steep learning curve but it is safe and effective procedure for managing BPH. In particular, effective haemostasis is the greatest advantage of BipolEP when compared to traditional TUR or laser enucleation.
