Factors affecting the effectiveness and success of retrograde holmium laser endopyelotomy as the primary treatment of ureteropelvic junction obstruction in adults.

PURPOSE: To evaluate the factors affecting the effectiveness, safety, and success of retrograde holmium:yttrium-aluminum-garnet laser endopyelotomy as the primary treatment of ureteropelvic junction obstruction in adults. METHODS: Adult patients who underwent retrograde holmium:yttrium-aluminum-garnet laser endopyelotomy as the primary treatment of ureteropelvic junction obstruction between January 2012 and June 2016 at our clinic were retrospectively analyzed. Success was defined as the relief of symptoms and the resolution of obstruction, as assessed via radiography. Factors affecting success were analyzed, such as the clinical characteristics, procedural outcomes, complications, and the type of ureteroscopy used in the procedure. RESULTS: Procedural success was achieved in 29 (74.4%) out of 39 patients, with a mean age of 38.3 ± 12.3 years during a median follow-up duration of 44 (33-65) months. Failure occurred at a median of 4.5 (3-22) months. It was detected that the presence of primary obstruction, ipsilateral kidney function being >30% of normal, and the length of obstruction being <1 cm positively affected procedural success (p = 0.009, p = 0.011, and p = 0.019, respectively). In the postoperative period, two Grade I and four Grade II complications were observed according to the Clavien-Dindo classification. There was a difference only in the operation time between semirigid (24) and flexible ureteroscopes (15), with the operation time being shorter with the use of a semirigid ureteroscope than with the use of a flexible uteroscope (p < 0.001). CONCLUSION: Retrograde holmium:yttrium-aluminum-garnet laser endopyelotomy is a minimally invasive method that can be used effectively and safely as the primary treatment of patients with ureteropelvic obstruction, when long-term results are also taken into consideration. The decision of performing laser endopyelotomy should be made after a detailed evaluation of the characteristics of the patient as well as of the obstruction.

Listening to music during arteriovenous fistula surgery alleviates anxiety: A randomized single-blind clinical trial.

BACKGROUND: Both end-stage renal disease and being wait-listed for a kidney transplant are anxiety-causing situations. Wait-listed patients usually require arteriovenous fistula surgery for dialysis access. This procedure is performed under local anesthesia. We investigated the effects of music on the anxiety, perceived pain and satisfaction levels of patients who underwent fistula surgery. AIM: To investigate the effect of music therapy on anxiety levels and perceived pain of patients undergoing fistula surgery. METHODS: Patients who were on a waiting list for kidney transplants and scheduled for fistula surgery were randomized to control and music groups. The music group patients listened to music throughout the fistula surgery. The State-Trait Anxiety Inventory was performed to assess anxiety, additionally visual analog scale was used to evaluate perceived pain, willingness to repeat the procedure and patient satisfaction. Demographic features, comorbidities, surgical history, basic surgical data (location of fistula creation, duration of surgery, incision length) and intra-operative hemodynamic parameters were recorded by an investigator blinded to the study group. An additional trait anxiety assessment was performed following the surgery. RESULTS: There was a total of 55 patients included in the study. However, 14 patients did not fulfill the criteria due to requirement of sedation during surgery or uncompleted questionnaires. The remaining 41 patients were included in the analysis. There were 26 males and 15 females. The control and music groups consisted of 20 and 21 patients, respectively. With regard to basic surgical and demographic data, there was no difference between the groups. Overall patient satisfaction was significantly higher and intra-operative heart rate and blood pressure were significantly lower in the music group (P < 0.05). Postoperative state anxiety levels were significantly lower in the music group. CONCLUSION: Music therapy can be a complimentary treatment for patients undergoing fistula surgery. It can reduce anxiety and perceived pain, improve intraoperative hemodynamic parameters and enhance treatment satisfaction, thus may contribute to better compliance of the patients.

The Role of Ciprofloxacin Resistance and Extended-spectrum beta-lactamase (ESBL) Positivity in Infective Complications Following Prostate Biopsy.

PURPOSE: To evaluate ciprofloxacin resistance (CR) and extended-spectrum beta-lactamase (ESBL) positivity in the rectal flora, antibiotic prophylaxis received, and post-biopsy infectious complications in patients undergoing prostate biopsy. MATERIAL & METHODS: Rectal swab samples collected from 99 patients suspected of prostate cancer two days before prostate biopsy were tested for microbial susceptibility and ESBL production. All patients were given standard ciprofloxacin and ornidazole prophylaxis. Ten days post-biopsy, the patients were contacted by phone and asked about the presence of fever and/or symptoms of urinary tract infection. RESULTS: Escherichia coli (E.coli) was the most common isolate detected in 82 (75%) of the rectal swab samples. Ciprofloxacin resistance was detected in 33% and ESBL positivity in 22% of the isolated E.coli strains. No microorganisms other than E.coli were detected in blood, urine, and rectal swab cultures of patients who developed post-biopsy complications. CR E.coli strains also showed resistance to other antimicrobial agents. The lowest resistance rates were to amikacin (n = 2, 7.4%) and nitrofurantoin (n = 1, 3.7%). Seven patients (7.6%) developed infectious complications. There was no significant difference in probability of hospitalization between patients with CR strains (14.3%) and those with ciprofloxacin-susceptible strains (14.3% vs. 4.7%; p = 0.194). However, strains that were both CR and ESBL-positive were associated with significantly higher probability of hospitalization compared to ciprofloxacin-susceptible strains (28.6% vs. 3.8%; p = 0.009). CONCLUSION: The higher rate of infectious complications with CR and ESBL-positive strains suggests that the agents used for antibiotic prophylaxis should be reevaluated. It is important to consider local resistance data when using extended-spectrum agents to treat patients presenting with post-biopsy infectious complications.

Is the Efficacy and Safety of Retrograde Flexible Ureteroscopy in the Elderly Population Different from Non-elderly Adults?

Background and objectives The population of elderly adults is increasing globally, and due to metabolic changes related to advanced age, many elderly adults experience kidney stones. Flexible ureteroscopy (f-URS) is a minimally invasive procedure to treat kidney stones, but it is not free of complications. The goals of this study were to analyze the efficacy and safety of f-URS in the management of kidney stones in patients aged ≥60 years and compare the outcomes of this surgery with the outcomes of the same surgery in a younger population. Materials and methods We retrospectively reviewed patient data from 1750 patients who met our inclusion criteria and received f-URS at the urology clinic of our hospital from 2012 to 2017. Patients were assigned into two groups: those aged ≥60 years (Group 1, n=291) and those aged 19-59 years (Group 2, n=1459). The perioperative results were evaluated comparatively. We performed multivariable analyses for factors predicting complications. Results When we compared the groups on demographic attributes, we noted statistically significant differences in gender, body mass index (BMI), and American Society of Anesthesiologists scores. Stone size and operation time were higher in the ≥60-year age group (Group 1). Other stone characteristics and operative features were similar. Stone-free rates (SFR) after the first procedure were 88.0% in Group 1 and 89.2% in Group 2. SFR and success rates at three months were similar for both groups. The complication rates were similar, and multivariable regression analysis revealed the most important factor affecting the complications was the presence of residual stones in both groups. The second most important factor affecting the complication was the operation time in Group 1 and the number of stones in Group 2. Conclusion In our study, there were no significant differences in terms of results and complications among elderly and young patients after f-URS except for the duration of the operation. The prolongation of operation time results in worse outcomes in terms of perioperative complications in patients aged ≥60 years. f-URS is a relatively safe and efficient procedure, with a small risk of minor complications even in the elderly population, with increased comorbidity.

Retrograde Intrarenal Surgery Following Laser Endopyelotomy; Sequential Procedures for Ureteropelvic Junction Obstruction and Nephrolithiasis.

PURPOSE: This study was designed to evaluate the effectiveness and safety of retrograde intrarenal surgery (RIRS)following retrograde laser endopyelotomy (rLEP) in concomitant ureteropelvic junction obstruction (UPJO) andstone disease. MATERIALS AND METHODS: Patients with concomitant UPJO and renal stone disease who were first treated in ourclinic by rLEP for obstruction and then RIRS for stone disease were enrolled. Study period went from 2012 to2017. RIRS following rLEP was performed earliest at the sixth week. Patients who underwent rLEP were matchedwith those with normal anatomy at a 1:1 ratio based on the propensity scores. Additionally, clinical results werecompared in order to evaluate the effects of rLEP surgery on RIRS. Subsequently, patients who underwent RIRSfollowing rLEP were independently evaluated and factors affecting the success of sequential procedures wereinvestigated. RESULTS: The sole difference between those that underwent RIRS following rLEP (n=27) and controls with normalanatomy that underwent RIRS was in operative times (p = .011). Evaluation of potential success factors inthe sequential rLEP-RIRS group revealed that primary etiology, obstruction length less than 1cm, smaller stonesize and presence of single stone showed significant effects (p = .047, p = .030, p = .040, p ? .001, respectively).RIRS following rLEP generated an 81.5% stone-free and, after a median follow-up time of 32 months, a 74.1%obstruction-free rate. CONCLUSION: RIRS following rLEP in patients with UPJO and renal stones is an effective treatment method. It canbe used safely in patients with single stones < 2cm, short obstruction lengths, and presence of primary etiology.

Bilateral intra-abdominal testicular tumor: Case report.

INTRODUCTION: Bilateral intra-abdominal testis is a very rare clinical entity. These testes may develop cancer in an adult patient with empty scrotum. CASE PRESENTATION: A case of a huge intra-abdominal solid mass in a 32-year-old gentleman is presented. Physical examination revealed an empty scrotum. Laboratory investigations, imaging studies, laparotomy and histopathological examination showed that the solid mass was a mixed germ cell tumor of the left testis. The contra-lateral testis also had a tumor. Resection of the solid mass and contra-lateral orchiectomy was performed. Adjuvant chemotherapy was given. Six months after surgery, his follow-up parameters were all within normal limits. DISCUSSION: Since bilateral intra-abdominal testis tumor is a very rare clinical entity, there are no patient management guidelines available. Management strategies differ significantly among groups and they are based mainly on the experience reflected in the context of anecdotal case reports. CONCLUSION: Surgical exploration and adjuvant chemotherapy seems as a reasonable treatment option in the setting of bilateral intra-abdominal testis tumor in an adult patient.
