The change in serum Thiol/Disulphide homeostasis after transrectal ultrasound guided prostate biopsy.

OBJECTIVES: The aim of this prospective clinical study was to investigate variations in a novel oxidative stress marker (thiol/disulphide homeostasis) in men who underwent transrectal ultrasound guided prostate biopsy (TRUSB). MATERIALS AND METHODS: A total of 22 men undergoing TRUSB of the prostate were enrolled in the study. Patients with abnormal digital rectal examination and/or total prostate specific antigen (PSA) over 4ng/mL underwent TRUSB with 12 cores. Serum samples were obtained before and just after the procedure to evaluate the possible changes in thiol/disulphide homeostasis. Mean age, total PSA and free PSA, prostate volume and histopathological data were also recorded. RESULTS: Mean age of the study population was 65.05±8.89 years. Significant decreases in native and total thiol levels were documented after the biopsy procedure. However, serum disulphide levels and disulphide/native thiol, disulphide/total thiol and native / total thiol ratios did not significantly change after TRUSB. No correlation was observed between oxidative parameters and total PSA and free PSA levels, prostate volume and histopathology of the prostate. However, mean patient age was significantly correlated with mean native and total thiol levels. CONCLUSION: Significant decreases in serum native and total thiol levels related to the prostate biopsy procedure suggest that TRUSB causes acute oxidative stress in the human body. Since our trial is the first in the current literature to investigate these oxidative stress markers in urology practice, additional studies are warranted.

Effects of Bladder Neck Plication on Climacturia After Robot-Assisted Laparoscopic Prostatectomy.

Purpose: The aim of this study is to investigate the effect of bladder neck plication during transperitoneal robot-assisted radical prostatectomy (tRARP) on orgasm-related incontinence (climacturia) and the relationship between International Index of Erectile Function 5 (IIEF-5) scores and climacturia. Materials and Methods: We evaluated 118 patients who underwent nerve-sparing tRARP in our clinic and survived the first postoperative year. Patients were divided into two groups: those who underwent bladder neck plication (Group 1, n = 58) and those who did not (Group 2, n = 60). Our study investigated whether there is a difference between the groups in terms of climacturia or if there is a relationship between IIEF-5 scores and climacturia. Results: Of the patients in Group 1, 10.3% had incontinence and 13.8% had climacturia. Of the patients in Group 2 who did not have bladder neck plication, 10% had incontinence and 15% had climacturia. There was no difference between the groups in terms of climacturia (P > .825). Three patients (5.2%) in Group 1 and four patients (6.6%) in Group 2 requested treatment. There was no statistically significant correlation between IIEF-5 scores and climacturia in both groups (Group 1, P > .208; and Group 2, P > .508). Conclusions: In our study, the frequency of climacturia in patients who underwent bladder neck plication during tRARP was consistent with the literature and did not show a statistically significant difference from patients who did not undergo bladder neck plication. It has been observed that bladder neck plication, which has no effect on long-term continence, does not contribute to prevention of climacturia. No correlation was found between IIEF-5 scores and climacturia.

Elderly Patients' Outcomes After Robot-Assisted Radical Prostatectomy: A Single Center Experience.

Aim: To assess the oncological and functional outcomes of patients aged 70 years or older after robot-assisted radical prostatectomy (RARP) and compare their results with younger men. Materials and Methods: Our study included 496 men who underwent RARP in our clinic between March 2015 and December 2021 with at least 1-year follow-up. Of these patients, 130 were aged 70 or older, and 366 were between 60 and 69. Preoperative characteristics, perioperative parameters, postoperative oncological, and functional results were studied. Results: The entire cohort (496 patients) aged 67 years on median (range 60-84), with a median prostate-specific antigen of 8.4 ng/mL. All the patients had a minimum 1-year of follow-up and the median follow-up was 32 months. According to the perioperative parameters, the two groups were similar except for hospital length of stay. On final pathology, the pathological stage, positive surgical margin rate and lymph node positivity were statistically not different between the two groups. The International Society of Urological Pathology grades were higher on final pathology for both groups, but this increase was greater in the ≥70 age group, and this was statistically significant (P = .013). In both groups, the median International Index for Erectile Function scores decreased after surgery significantly (P < .001), and at the 1st year follow-up, the decrease between the two groups was not different (0.973). Concerning continence outcomes, pad-free continence was significantly better in the 60-69 age group (94.5%) compared to the ≥70 age group (93.1%). Conclusions: The perioperative safety, oncological, and functional results of RARP in elderly men are comparable to younger patients. Clinical trial registiration number: (30/06/2022-13/24).

Should Peritoneal Re-Approximation Be Performed After Transperitoneal Robot-Assisted Radical Prostatectomy?

Background: The aim of the study is to examine the effect of peritoneal re-approximation or non-approximation on the postoperative course of patients at the end of transperitoneal robot-assisted radical prostatectomy (tRARP). It is also aimed to examine the relationship between peritoneal re-approximation or non-approximation and drain removal time, need for analgesics, passage of flatus, and length of hospital stay. Methods: A total of 247 patients who underwent tRARP by 2 different experienced surgeons were included in the study. At the end of the tRARP procedure, 1 surgeon performed peritoneal re-approximation (Group 1, n = 108), whereas the other performed peritoneal non-approximation (Group 2, n = 139). The effect of the procedures on drain removal time, passage of flatus, need for analgesics, and length of hospital stay were compared between the groups. Results: There was no significant difference between the groups in terms of preoperative parameters including age, body mass index, and preoperative prostate-specific antigen levels (P > .05) (P = .622, P = .126 and P = .591, respectively). No statistically significant difference was found between the two groups in terms of comorbidity, Gleason score, clinical stage, and lymph node dissection (P = .086, P = .344, P = .318, P = .587, respectively). There was no statistically significant difference between the groups in terms of drain removal time, need for analgesics, passage of flatus, and length of hospital stay (P = .095, P = .142, P = 95, P = .389, respectively). Conclusion: This study did not demonstrate any additional postoperative benefit of peritoneal re-approximation. It has been shown that peritoneal re-approximation has no effect on the length of hospital stay, the need for pain relievers, and passage of flatus, drain duration, day. Therefore, we do not recommend re-approximation of the peritoneum.

Incidence of ureteral stricture after ureterorenoscopic pneumatic lithotripsy for distal ureteral calculi.

BACKGROUND AND PURPOSE: We investigated the incidence of ureteral stricture in patients treated with ureterorenoscopic pneumatic lithotripsy for distal ureteral calculi. PATIENT AND METHODS: Between April 2006 and January 2009, 154 patients requiring ureterorenoscopic pneumatic lithotripsy for distal ureteral calculi were enrolled into the study. We evaluated the stone size, impaction of a stone, the need for ureteral orifice dilatation and the need for application of double-J stent. RESULTS: A total of 154 patients underwent URS-PL for ureteral calculi. Mean calculi diameter was 12.17 +/- 2.54 (range: 5-20 mm). Stone free rates after the first URS-PL operation were 97.4% of patients. In 2 patients (1.29%), ureteral perforation occurred as an early complication. We observed deep mucosal injury in 9 patients (5.84%). Partial stricture (partial obstruction) was observed in 9 patients (5.84%). Of 9 patients who had an ureteral stricture postoperatively, 7 patients had ureteral calculi > or = 10 mm, 2 patients had calculi < 10 mm. We observed ureteral stricture in 2 (8.69%) out of 23 patients who had calculi < 10 mm, and in 7 (5.34%) out of 131 patients who had calculi > or = 10 mm (p > 0.05). Ureteral stricture was observed in 2 (13.33%) out of 15 patients who had impacted calculi, and in 7 (5.03%) out of 139 patients who did not have impacted calculi (p < 0.05). We observed ureteral stricture in 3 (6.25%) out of 48 patients who required ureteral dilatation, and in 6 (5.66%) out of 106 patients who did not require ureteral dilatation (p > 0.05). Ureteral stricture was observed in 6 (15%) out of 40 patients who required ureteral double-J catheter placement, and in 3 (2.63%) out of 114 patients who did not require ureteral double-J catheter placement (p < 0.05). CONCLUSION: The results of our study have demonstrated that the success rate was not related to the stone dimension, but the time of operation was found to be increased with larger stones. Main risk factors for formation of ureteral stricture were impacted ureteral calculi and reasons which merits double-J catheter placement like mucosal damage, perforation, impacted calculi and high stone burden.

Effectiveness of acupuncture in patients with category IIIB chronic pelvic pain syndrome: a report of 97 patients.

OBJECTIVE: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is of significant interest in urology and unfortunately, the therapy modalities recommended are not fully effective. Therefore, we undertook a pilot study to determine whether acupuncture improves the pain, voiding symptoms, and quality of life in men with category IIIB CP/CPPS. DESIGN: Prospective, one-group trial, cohort study. SETTING: Outpatient urology clinic. PATIENTS AND INTERVENTIONS: Ninety-seven CP/CPPS patients received six sessions of acupuncture to the BL-33 acupoints once a week. The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was completed by each patient before and after the treatment and on 12th and 24th weeks following the treatment. OUTCOME MEASURES: Mean values of total CPSI score, pain subscore, urinary subscore, and quality of life subscore after the treatment and on follow-up after the treatment were compared with the baseline values. RESULTS: There was a statistically significant decrease in all of the subscores evaluated at all periods compared with the baseline. Eighty-six patients out of 93 (92.47%) were NIH-CPSI responders (more than 50% decrease in total NIH-CPSI score from baseline) at the end of the treatment. CONCLUSIONS: The results of this study suggest that acupuncture appears to be a safe and potentially effective treatment in improving the symptoms and quality of life of men clinically diagnosed with CP/CPPS.

Does extracorporeal shock wave lithotripsy-related pain get affected by menstrual cycle and menopause?

The objective of the study was to investigate the effect of the menstrual cycle and menopause on extracorporeal shock wave lithotripsy (ESWL)-related pain outcome. Since March 2017, we evaluated a total of 145 women who underwent the first session of ESWL for renal or ureteral stones. Patients were divided into two groups, as menstruating and menopaused women. For menstruating women, the number of days between the last day of mens and ESWL was noted and women were separated as in the follicular phase (1-14 days) or in the luteal phase (15-30 days) of menstruation. To control these two female groups, 149 men of similar age were included in the study. After the procedure, the experienced pain was recorded on a ten-point visual analog scale (VAS) by the patient and they also rated the severity of pain as no, mild, tolerable, and intolerable on the pain questionnaire. The mean age of the patients was 43 ± 15 years for the female group and 42 ± 13 years for the male group. While stone burden was not different between the female and male groups (p = 0.459), VAS score was not statistically different between genders (p = 0.293). However, men reported a higher rate of mild pain, while women reported a higher rate of tolerable pain (p = 0.008) in the pain questionnaire. Mean VAS score was significantly lower for the menopaused women group than menstruating women, young and old men (p = 0.001). In a subgroup analysis, menopaused women group reported lower VAS score and better pain questionnaire result than menstruating women (p < 0.001). There was no statistically significant difference between the follicular and luteal phase of the menstrual cycle in terms of mean VAS score and pain questionnaire results (p = 0.891 and 0.441, respectively). When compared with the young men group, the only significant difference was pain questionnaire results between women in the luteal phase (p = 0.014). Multiple regression analysis showed that only menstruation (ß = 0.639, p < 0.001) was an independent factor for VAS score. Menstrual cycle phase had no effect on pain perception during the ESWL session and menopaused women felt less pain than menstruating women during this procedure. The control male group showed that the reduction of ESWL-related pain in menopause was not related to aging.

Robotic radical cystectomy for the management of bladder cancer: Analysis of operative and pathological outcomes of eighteen patient.

OBJECTIVE: To present the surgical and pathological results of robotic radical cystectomy (RRC) operations performed in our clinic. MATERIAL AND METHODS: A total of 18 patients, who underwent RRC and intracorporeal urinary diversion between October 2016 and September 2017 for clinically localized bladder cancer in our clinic, were included in the study. The results were evaluated under three headings. 1. operative outcomes (total operation time, perioperative blood loss, postoperative hematocrit decrease) 2. recovery period (pull-off drain day, hospitalization time) 3. oncological results (pathologic stage, surgical margin, number, and characteristics of lymph nodes removed). Complications within the postoperative 30-day period, were evaluated and the Clavien classification system was used to classify the complications. RESULTS: The mean age of the patients was 64.4 (52-80) years. Seventeen male patients and one female patient underwent robotic cystectomy. At the operative outcomes, the mean blood loss was 325 mL, and the mean hematocrit decrease was 3.15%. The mean duration of the surgery was 471 minutes (330-630), while the median operative time was 450 minutes. Complications occured in 6 patients during the early postoperative period. Six of them (75%) had minor complications (Clavien grade 1), two patients (25%) had major complications (Clavien grade 4). CONCLUSION: Our initial experience with RRC is that, this surgical technique has acceptable operative, oncological and short-term clinical outcomes. However, prospective randomized studies are needed to assess whether there is a clear advantage compared to open surgery.

Rare cause of adult female incontinence: complete duplication of the collecting system and ectopic ureter of the kidney draining into the vagina treated by laparoscopic upper pole heminephrectomy and ureterectomy.

A 38-year-old woman presented with a lifelong history of involuntary urinary leakage. The patient reported that she had been operated for her urinary leakage with the diagnosis of stress incontinence with transobturator tape two times at two different institutions. Preoperative computed tomography scan showed complete duplication of the left kidney with poorly functioning upper pole and a tortuous left dilated ureter running down and opening into the vagina. Laparoscopic left upper pole heminephrectomy and ureterectomy were performed uneventfully. Her incontinence improved immediately after surgery.
