RESUMEN
PURPOSE: Renal cysts are typically a benign condition, and parapelvic cysts are a type of renal cyst that occur adjacent to the renal pelvis or renal sinus. Parapelvic cysts can increase the risk for injury to adjacent organs or urine leakage during laparoscopic surgery. Flexible ureteroscopes with laser assistance were used to make internal incisions in cysts. Perioperative outcomes of this method were compared with those of laparoscopic surgery. METHODS: Eight-three patients, who underwent surgical treatment for renal cysts at the authors' medical center between January 2019 and June 2022, were evaluated. Two patients were excluded because they originally opted for RIRS but subsequently converted to laparoscopic surgery. Patients were divided into 2 groups based on surgery type: laparoscopic; and RIRS for internal incision. Outcomes in both groups were analyzed. RESULTS: Of the 81 patients analyzed, 60 [74% (group 1)] underwent laparoscopic surgery and 21 [26% (group 2)] underwent RIRS for internal incision. The median operative durations for groups 1 and 2 were 87 and 56 min, respectively (p < 0.001). Relative to RIRS, laparoscopic surgery resulted in greater postoperative painkiller use (laparoscopic surgery versus [vs.] RIRS, 43% vs. 19%; p = 0.047). The median length of hospital stay was 2 and 1 days, respectively (p < 0.001). CONCLUSIONS: RIRS demonstrated several advantages over laparoscopic surgery for the internal incision of parapelvic cysts, including shorter operative duration, shorter hospital stay, and less postoperative pain control. These findings may guide the selection of appropriate surgical approaches for patients with renal cysts.

Lower urinary tract symptoms (LUTS), such as urgency, urinary incontinence, and/or difficulty voiding, hamper the quality of life (QoL) of patients with spinal cord injury (SCI). If not managed adequately, urological complications, such as urinary tract infection or renal function deterioration, may further deteriorate the patient's QoL. Botulinum toxin A (BoNT-A) injection within the detrusor muscle or urethral sphincter yields satisfactory therapeutic effects for treating urinary incontinence or facilitating efficient voiding; however, adverse effects inevitably follow its therapeutic efficacy. It is important to weigh the merits and demerits of BoNT-A injection for LUTS and provide an optimal management strategy for SCI patients. This paper summarizes different aspects of the application of BoNT-A injection for lower urinary tract dysfunctions in SCI patients and provides an overview of the benefits and drawbacks of this treatment.

BACKGROUND: Staghorn stones require surgical treatment to prevent serious complications. Multitract percutaneous nephrolithotomy (PNL) causes great renal parenchymal injury and blood loss. One-stage endoscopic combined intrarenal surgery (ECIRS) entails the combined use of antegrade nephroscope and retrograde flexible ureteroscope to clear the staghorn stone, which may overcome the limitations of multitract PNL. We aimed to compare the perioperative outcomes of mini ECIRS and multitract minimally invasive PNL in staghorn stone management. METHODS: This was a retrospective single-center study of patients with staghorn stones who underwent ECIRS (n = 17) or multitract minimally invasive PNL (n = 17) between January 2018 and September 2021. RESULTS: There was a significant between-group difference with respect to Guy's stone score. Stone size, stone burden (ECIRS group, 21.41 cm3; multitract minimally invasive PNL group, 20.88 cm3 [P = 0.94]), and degree of hydronephrosis were comparable in the two groups. There was no significant between-group difference with respect to one-step or final stone-free rates. The mean operative time was also not significantly different between the groups (ECIRS group, 140 min; multitract minimally invasive PNL group, 183 min [P = 0.63]). ECIRS was associated with significantly lesser postoperative pain (visual analog scale; ECIRS group: 0; multitract minimally invasive PNL group: 2.7 [P < 0.001]). Hemoglobin loss, postoperative blood transfusion rate, complications, and length of hospital stay were comparable in the two groups. CONCLUSION: Both mini ECIRS and multitract minimally invasive PNL were effective and safe for the management of renal staghorn stones with comparable operation time and stone-free rate, and complications. ECIRS was associated with less severe postoperative pain.

Erectile dysfunction (ED) is an agonizing complication of diabetes mellitus (DM) and it is challenging to treat ED in DM patients. Platelet-rich plasma (PRP) is a unique therapeutic strategy comprising intrinsic growth factors. An attempt was made to explore the potentiality of the PRP treatment in DM-induced ED rats in various groups (control, DM-non-ED, DM-ED, and DM-ED treated with PRP). Streptozotocin (STZ) was used to induce DM in rats. The blood glucose levels of the DM rats were maintained at >300 mg/dl. In the 18-week experiment, survival rate, body weight, intracavernous pressure (ICP) variations, and arterial blood pressure were analyzed. The tissue restoration results were validated by histological, immunofluorescence, and transmission electron microscopic analysis. PRP treatment of DM-ED rats significantly increased all parameters of erectile function compared to pre-treatment of PRP and DM-ED treated with vehicle. The histological results revealed that PRP treatment substantially enhanced the regeneration of myelinated nerves and decreased the atrophy of corporal smooth muscle. Notably, the PRP treatment immensely enhanced the survival rate in post-surgery DM-ED rats. These results indicated certain benefits of PRP treatment in delaying damage and preventing post-surgery complications in DM patients. Hence, PRP treatment is a novel multifactorial strategy for DM-ED patients.

PURPOSE: In recent years, second-look transurethral resection of bladder tumors (TURBT) has been recommended for patients with stage T1 bladder cancer after the initial TURBT for restaging and deciding the subsequent treatment. However, we believe that second-look TURBT has therapeutic benefits, such as low incidence of recurrence and progression. Therefore, we compare the differences in long-term outcome between patients who did and did not accept second-look TURBT for stage T1 bladder cancer. METHODS: We assessed 504 patients diagnosed with urothelial carcinoma who underwent initial TURBT between January 2012 and December 2016 at a single medical center; of these patients, 177 were diagnosed with T1 bladder cancer during the initial TURBT, and we excluded no muscle from the specimen in the initial TURBT. The patients were categorized into groups 1 and 2 based on the acceptance of second-look TURBT, which was performed within 4-14 weeks after the initial TURBT. Group 1 underwent second-look TURBT, but group 2 did not. Both groups were followed-up for recurrence-free survival (RFS) and progression-free survival (PFS), and the risk factors for recurrence and progression were analyzed. RESULTS: In total, 93 (52.5%) patients in group 1 underwent second-look TURBT, and 84 (47.5%) in group 2 did not. The 2-year RFS rates were 74.6% and 60.0% and the PFS rates were 91.2% and 87.5% in groups 1 and 2, respectively. CONCLUSION: This study demonstrated higher recurrence-free and progression-free survival rates for patients who underwent second-look TURBT. This result emphasizes the importance of second-look TURBT in stage T1 bladder cancer not only for restaging but also for therapeutic benefit.

OBJECTIVE: The aim of this study is to investigate the treatment outcome in men with detrusor underactivity (DU) and voiding dysfunction who underwent transurethral resection or incision of the prostate (TURP or TUIP). DU usually affects decision making whether bladder outlet surgery is necessary. MATERIALS AND METHODS: A total of 60 men with urodynamic DU and voiding dysfunction who underwent TURP or TUIP from 1998 to 2015 were retrospectively analyzed for their treatment outcome after follow-up for more than 1 year. DU was defined as urodynamic evidence of low detrusor pressure (<40 cm H2O), low flow rate (<10 mL/s), a postvoid residual urine volume >300 mL, and a voiding efficiency (VE) of <33%. Satisfactory outcome was defined as improved quality of life and having a VE of >50% after treatment. Predictive factor for a successful outcome was also analyzed. RESULTS: At a mean follow-up of 31 months, 49 (81.7%) patients had achieved a satisfactory treatment outcome. Among the patients who received TURP and TUIP, 38/44 (86.4%) and 11/16 (68.8%) had satisfactory outcome, respectively. The satisfactory group had significantly higher detrusor pressure and greater bladder compliance at baseline than the unsatisfactory group. There was significant improvement in the urodynamic parameters after treatment in the satisfactory group. Among the patients with satisfactory outcome, 34 (69.4%) patients had recovery of detrusor function within 3 months. CONCLUSION: Active surgical treatment such as TURP or TUIP results in recovery of VE and detrusor function within 3 months after treatment in the majority of patients with DU.

PURPOSE: To evaluate the prevalence of lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) in the illicit male ketamine abusers (KA). MATERIALS AND METHODS: The male street KAs caught by policemen and patients visiting urologic clinics were invited to answer a structured questionnaire including demographic data, illicit drug use related details (duration, frequency, dosage and abstinence status), international prostate symptoms score (IPSS), interstitial cystitis symptoms and problem index (ICSI and ICPI) and International index of erectile function (IIEF-5). Erectile dysfunction was defined as IIEF-5 â¦21. RESULTS: Finally, we included 1056 participants (993 street, 63 hospital KAs) with a mean age of 27.4 ±6.2 years. ED presented in 30.8% of all KAs. and Hospital KAs were more subject to having ED than street KAs (69.6% vs. 28.0%, p<0.01). Multi-variate analysis revealed that risk factor for male ED were age â§30 years (OR = 1.765). Subgroup analysis on male street KAs disclosed that abstinence â§3 months is a protective factor for ED. Lower urinary tract symptoms (ICSI+ICPI â§12) was prevalent in KAs and multivariate analysis disclosed that significant risk factors for LUTS (ICSI+ICPI â§12) were age â§30 years, duration â§24 months and co-use of other illicit drugs. CONCLUSIONS: Male ED and LUTS were frequently observed in the ketamine abusers. We suggested that street ketamine abuse should be considered in young men presented with ED and LUTS in the clinics.
