RESUMO

Male hypogonadism (MH) is a clinical and biochemical syndrome caused by inadequate synthesis of testosterone. Untreated MH can result in long-term effects, including metabolic, musculoskeletal, mood-related, and reproductive dysfunction. Among Indian men above 40 years of age, the prevalence of MH is 20%-29%. Among men with type 2 diabetes mellitus, 20.7% are found to have hypogonadism. However, due to suboptimal patient-physician communication, MH remains heavily underdiagnosed. For patients with confirmed hypogonadism (either primary or secondary testicular failure), testosterone replacement therapy (TRT) is recommended. Although various formulations exist, optimal TRT remains a considerable challenge as patients often need individually tailored therapeutic strategies. Other challenges include the absence of standardized guidelines on MH for the Indian population, inadequate physician education on MH diagnosis and referral to endocrinologists, and a lack of patient awareness of the long-term effects of MH in relation to comorbidities. Five nationwide advisory board meetings were convened to garner expert opinions on diagnosis, investigations, and available treatment options for MH, as well as the need for a person-centered approach. Experts' opinions have been formulated into a consensus document with the aim of improving the screening, diagnosis, and therapy of men living with hypogonadism.

RESUMO

Aim: To conduct a comparative, nonrandomized study to assess the feasibility of mini-Endoscopic Combined Intrarenal Surgery (ECIRS) using supine Mini-percutaneous nephrolithotomy (PCNL) access (16F) in Galdakao-Modified Supine Valdivia position for managing proximal large-volume impacted ureteral calculi as ambulatory day-care surgery vis-a-vis standalone ureteroscopy (URS) with push-back PCNL, if needed. The primary aim was to study the outcomes and stone-free rates (SFRs). Secondary aim was to compare the intraoperative and short-term postoperative complications. Materials and Methods: Data of 60 patients undergoing ECIRS (Group 1) from January 2016 to December 2019 were collected prospectively in a nonrandomized fashion from a single center after Ethics Committee approval. A matched-paired analysis was performed with retrospectively collated data of 60 patients undergoing standard URS/pushback PCNL (Group 2) using analysis of variance, Fisher's exact test, and Chi-square test. p < 0.05 was considered statistically significant. Outcomes and Results: Group 1 patients had a significantly shorter procedure time vs Group 2 (42.1 ± 11.2 minutes vs 52.1 ± 13.7 minutes; p < 0.001). Group 1 (59/60) patients had an overall single stage SFR of 98.3%, which was significantly higher than single-stage SFR of 83% in Group 2 (50/60) (p < 0.002). Group 2 patients had a higher incidence of fever (10 vs 4, p = 0.01). However, there were no cases of sepsis in either group. Rest of the complications were comparable for both, as the need for ancillary procedures was significantly higher in Group 2 (10% vs 1.7%, p < 0.001). Patients were discharged on the same day in both groups. Conclusions: The findings of our study suggest that, in large and impacted proximal ureteric stones, combined minimally invasive endoscopic approach offers the best option to render the patient stone free by a single intervention. With better intra- and postoperative outcomes and safety profile, Mini-ECIRS may be considered as an ambulatory procedure in this setting.

RESUMO

Transurethral resection of prostate (TURP) has been the "gold standard" for surgical removal of the enlarged prostatic adenoma for many decades, and is likely to remain so despite the advent of multiple minimally invasive alternative procedures. TURP has stood the test of time, whereas the alternatives have come and gone in succession, as we have witnessed over the years. The accompanying video demonstrates the complete steps of TURP in a case of prostatic adenoma, highlighting the important nuances of the principles and the technique of resection.

RESUMO

Management of urolithiasis in an ectopic pelvic kidney is challenging and laparoscopic pyelolithotomy and laparoscopy-guided percutaneous nephrolithotomy (PCNL) are commonly favored options. We report a case of ultrasound-guided supine mini-PCNL in ectopic pelvic kidney in an adolescent female. Complete stone clearance was achieved with an uneventful postoperative period. Ultrasound-guided supine mini-PCNL is safe and effective treatment option for the management of calculus in the ectopic pelvic kidney. The risk of injury to surrounding structures associated with ultrasound modality of access can be avoided with proper case selection and careful technique.

RESUMO

OBJECTIVE: To evaluate whether there would be a difference in outcome when the smaller ultra-mini 12 Fr sheath was used instead of the mini 16 Fr sheath for percutaneous nephrolithotomy (PCNL) in paediatric patients for stones less than 25 mm. METHODS: This was a prospective cohort study of patients who underwent PCNL in our hospital in a 2-year period from July 2016 to June 2018 by a single surgeon. PCNL was performed in a prone position and tract was dilated to the respective size using single step dilatation. Laser was used to fragment the stone. Stone-free outcome was defined as absence of stone fragment at 3 months on kidney, ureter, and bladder X-ray. RESULTS: There were 40 patients in each group. Mean stone size was comparable between the two groups (14.5 mm vs. 15.0 mm). The procedure was completed faster in the 16 Fr group compared to 12 Fr group (24.5 min vs. 34.6 min). Stone clearance was highly successful in both groups (97.5% vs. 95.0%). There was no difference in complications between the two groups. The decrease in hemoglobin was minimal in both groups (0.2 g/dL vs. 0.3 g/dL). CONCLUSION: We found that the success rates were similar in both mini PCNL and the smaller ultra-mini PCNL groups. No significant difference in bleeding was noted in our pilot study, however, operative time was longer in the ultra-mini group as compared to the mini sheath group.

RESUMO

The International Alliance of Urolithiasis (IAU) would like to release the latest guideline on percutaneous nephrolithotomy (PCNL) and to provide a clinical framework for surgeons performing PCNLs. These recommendations were collected and appraised from a systematic review and assessment of the literature covering all aspects of PCNLs from the PubMed database between January 1, 1976, and July 31, 2021. Each generated recommendation was graded using a modified GRADE methodology. The quality of the evidence was graded using a classification system modified from the Oxford Center for Evidence-Based Medicine Levels of Evidence. Forty-seven recommendations were summarized and graded, which covered the following issues, indications and contraindications, stone complexity evaluation, preoperative imaging, antibiotic strategy, management of antithrombotic therapy, anesthesia, position, puncture, tracts, dilation, lithotripsy, intraoperative evaluation of residual stones, exit strategy, postoperative imaging and stone-free status evaluation, complications. The present guideline on PCNL was the first in the IAU series of urolithiasis management guidelines. The recommendations, tips and tricks across the PCNL procedures would provide adequate guidance for urologists performing PCNLs to ensure safety and efficiency in PCNLs.

RESUMO

BACKGROUND: The aim of this study was to reach a consensus in the classification and standardized reporting for the different types of PCNLs. METHODS: The RAND/UCLA appropriateness methodology was used to reach a consensus. Thirty-two statements were formulated reviewing the literature on guidelines and consensus on PCNLs, and included procedure specific details, outcome measurements and a classification for PCNLs. Experts were invited to two rounds of input, the first enabled independent modifications of the proposed statements and provided the option to add statements. The second round facilitated scoring of all statements. Each statement was discussed in the third round to decide which statements to include. Any suggestion or disagreement was debated and discussed to reach a consensual agreement. RESULTS: Twenty-five recommendations were identified to provide standardized reporting of procedure and outcomes. Consensual scoring above 80% were strongly agreed upon by the panel. The top treatment related outcomes were size of sheath used (99.1%) and position for PCNL (93.5%). The highest ranked Outcome Measures included definition of postoperative hospital length of stay (94.4%) and estimated blood loss (93.5%). CONCLUSIONS: The consensus statements will be useful to clarify operative technique, in the design of clinical trials and standardized reporting, and presentation of results to compare outcomes of different types of PCNLs.

RESUMO

INTRODUCTION: Bladder stones in children can often be challenging to manage. We present our experience of minimally invasive percutaneous cystolithotripsy using 'mini-perc' instruments in the treatment of the bladder stones in pre-school children. The study also compares the outcomes of mini-percutaneous cystolithotripsy (mPCCL) and transurethral cystolithotripsy (TUC). OBJECTIVE: We hypothesized that mPCCL is a new minimally invasive technique with comparable outcomes to TUC. STUDY DESIGN: After parental consent and institutional review board approval, consecutive pre-school children with bladder stones were included from January 2011-December 2018. We shifted from the TUC to mPCCL in 2014, with mPCCL introduced as a new technique. Outcomes including stone free rate (SFR) and complication rates were compared for patients aged between 1 and 5 years of age who underwent mPCCL or TUC. RESULTS: A total of 31 patients (16 patients in Group 1 (mPCCL) and 15 patients in Group 2 (TUC) underwent the procedure. The mean age, stone size and operative times were 2.4 ± 0.96 years and 3.8 ± 0.77 years; 1.86 ± 0.65 cm and 1.34 ± 0.52 cm; and 33.5 ± 8.42 min and 38.2 ± 6.76 min for groups 1 and 2 respectively. While there were no intra or post-operative complications in group 1, in group 2 one patient required conversion to mPCCL due to difficulty in fragment removal per urethra and one with residual fragment needed repeat cystoscopy and fragment removal (Clavien IIIb). All patients in both groups were discharged the following day after catheter removal and remained stone free at 1- and 6-month follow-up. DISCUSSION: Our study shows good outcomes in managing bladder stones with the use of both TUC and mPCCL. We shifted from the former to mPCCL in 2014 during which there was an overlap of both these techniques, while mPCCL was being introduced. Subsequently, all stones have been managed with mPCCL without the need to revert back to TUC. In Group 1, we performed mPCCL, where the puncture was performed under ultrasound-guidance and fragment retrieval was accomplished with the vacuum-cleaner effect through the operating sheath. Complete stone clearance was achieved in all cases with no complications or need for secondary procedures. Limitations of our study include small sample size, single-centre experience, and lack of randomization. Further prospective randomized multicenter studies may be required to validate our results. CONCLUSION: The technique of percutaneous suprapubic cystolithotripsy using mini-nephroscope is an alternate to transurethral cystolithotripsy. While both these techniques are suitable for smaller bladder stones, PCCL may be considered as the preferred management option of especially large bladder calculus in preschool children.

RESUMO

Introduction: Pediatric upper urinary tract calculi can be treated by ureteroscopy (URS) or mini-percutaneous nephrolithotomy (mPCNL). We wanted to compare outcomes of URS and mPCNL from two tertiary referral centers that specialized in one of these treatments for pediatric stone disease. Materials and Methods: Data were collected from two tertiary centers for a 10-year period (2010-2019); one center specializing in URS and the other in mPCNL for consecutive patients ≤16 years undergoing either of these minimally invasive interventions. Upper urinary tract stones included stones in the kidney, pelviureteral junction, and proximal ureter, whereas mid or distal ureteral stones were excluded. Data were collected on patient and stone demographics. Outcomes of interest included stone-free rate (SFR) and complication rates. Results: During the study period, 55 patients underwent URS (group 1) and 40 patients underwent mPCNL (group 2). The mean stone size for groups 1 and 2 were 11.4 and 14.5 mm, respectively, whereas twice as many patients in group 1 had multiple stones. The final SFR and complication rates for groups 1 and 2 were 100% and 97.5%, and 5.4% and 12.5%, respectively. Although there were two Clavien II and one Clavien IV complication in the URS group, all five complications in mPCNL group were Clavien I. Conclusions: Our study shows excellent outcomes for upper urinary tract stones with both URS and mPCNL. Although treatment choices should be tailored to patients, each modality carries different advantages and our results reflect that high-volume centers specializing in a particular technique offer best outcomes, and this must also be borne in mind when counseling patients.

RESUMO

OBJECTIVES: To compare the safety and effectiveness of super-mini-percutaneous nephrolithotomy (SMP) and retrograde intrarenal surgery (RIRS) for the treatment of 1-2 cm lower-pole renal calculi (LPC). PATIENTS AND METHODS: An international multicentre, prospective, randomised, unblinded controlled study was conducted at 10 academic medical centres in China, India, and Turkey, between August 2015 and June 2017. In all, 160 consecutive patients with 1-2 cm LPC were randomised to receive SMP or RIRS. The primary endpoint was stone-free rate (SFR). Stone-free status was defined as no residual fragments of ≥0.3 cm on plain abdominal radiograph of the kidneys, ureters and bladder, and ultrasonography at 1-day and on computed tomography at 3-months after operation. Secondary endpoints included blood loss, operating time, postoperative pain scores, auxiliary procedures, complications, and hospital stay. Postoperative follow-up was scheduled at 3 months. Analysis was by intention-to-treat. The trial was registered at http://clinicaltrials.gov/ (NCT02519634). RESULTS: The two groups had similar baseline characteristics. The mean (sd) stone diameters were comparable between the groups, at 1.50 (0.29) cm for the SMP group vs 1.43 (0.34) cm for the RIRS group (P = 0.214). SMP achieved a significantly better 1-day and 3-month SFR than RIRS (1-day SFR 91.2% vs 71.2%, P = 0.001; 3-months SFR 93.8% vs 82.5%, P = 0.028). The auxiliary procedure rate was lower in the SMP group. RIRS was found to be superior with lower haemoglobin drop and less postoperative pain. Blood transfusion was not required in either group. There was no significant difference in operating time, hospital stay, and complication rates, between the groups. CONCLUSIONS: SMP was more effective than RIRS for treating 1-2 cm LPC in terms of a better SFR and lesser auxiliary procedure rate. The complications and hospital stay were comparable. RIRS has the advantage of less postoperative pain.

RESUMO

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) has undergone significant changes in recent years in the quest for improving efficacy and reducing morbidity. Newer minimally-invasive modalities of PCNL such as mini-PCNL, ultra-mini PCNL, and micro-PCNL have evolved with advancement in optics and technology. However, with these newer advancements, migration of small fragments produced with laser lithotripsy remains a concern, which may result in incomplete stone clearance. We describe a new technique of PCNL termed "Superperc", that utilizes suction to remove all the fragments and maintain one-way flow. METHODS: This was a prospective observational study involving 52 consecutive patients who underwent PCNL with the Superperc technique from April 2014 to June 2015. Surgery was performed using a pediatric ureteroscope used as a nephroscope and a specially designed sheath with a suction attachment. The Superperc uses a 10/12 F tract size, specially designed Superperc sheath (Shah Sheath) with suction mechanism and a pediatric ureteroscope (4.5/6 Fr, Richard Wolf) as nephroscope. RESULTS: The mean age of the group was 41.8 years (range 6-84) with 33 males and 19 females. Mean stone size was 19.11 mm (range 10-37 mm) and mean operative time was 40.9 min (range 26-92 min). Twenty-seven renal units had upper calyceal puncture, whereas 12 had middle, 8 lower calyceal and 5 had two punctures. DJ stent was placed in 20 patients, whereas 32 patients were totally tubeless. Only three patients required a nephrostomy tube. The mean hemoglobin drop was 0.32 g with no blood transfusion. Postoperatively, three patients had a mild fever and one had transient hematuria. The stone clearance rate in our study was 96.15% and the mean hospital stay was 31.5 h (range 22-76 h). CONCLUSION: Superperc is a new technique of minimally-invasive PCNL and can be successfully done with minimal modification in armamentarium, with the potential advantage of good stone clearance.

RESUMO

OBJECTIVE: To assess the feasibility and safety of a novel flexible mini-nephroscope in minimally invasive percutaneous nephrolithotomy (PCNL). Presumably, limiting the size and number of tracts during PCNL has the potential of decreasing the morbidity of the procedure. We present our experience with this new technique. MATERIALS AND METHODS: A retrospective analysis of patients with multiple kidney stones treated with mini-PCNL combined with a novel flexible mini-nephroscope was performed. Minimally invasive PCNL was done with rigid 12 F MIP-M nephroscope, followed by flexible mini-nephroscopy for smaller stones in other inaccessible calyces. Record was made of the operating time, stone-free rates, postoperative pain, morbidity, hospital stay, time to recovery, complication rates, and ancillary procedures. Matched-pair analysis was done with cases operated by flexible ureteroscopy performed with Flex X-2 or Flex X-c scope. RESULTS: Twenty-five patients in the study group were matched with 25 cases from the flexible ureteroscopy group. Both groups were comparable in terms of age, laterality, and mean composite stone burden. The mean operating time was 40.1 ± 10.6 minutes in the mini-PCNL group and 51.2 ± 8.8 minutes in the flexible ureteroscopy group. Mean hospital stay was similar in both groups. The primary stone clearance rate of 92% (23 of 25) in the mini-PCNL group was better than the clearance rate of 80% (20 of 25) in the flexible ureteroscopy group. Eight percent in the mini-PCNL group required ancillary procedures as compared with 20% of cases in the flexible ureteroscopy group. Postoperative pain and analgesia requirement in these patients was minimal. There were no significant complications. CONCLUSION: Flexible mini-nephroscope is an effective adjuvant to minimally invasive PCNL in achieving high clearance rate with minimum morbidity.

RESUMO

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) has witnessed rapid advancements, the latest being ultra-mini-percutaneous nephrolithotomy (UMP), which makes the use of 11-13F sheaths as compared to 24-30F sizes used in conventional PCNL. This miniaturization aims to reduce morbidity and improve patient outcomes. We evaluated the safety and efficacy of UMP and report our ourtcomes. PATIENTS AND METHODS: A total of 120 patients underwent UMP from July 2012 to March 2014. These patients had a single unilateral renal stone measuring between 8 and 20 mm. All patients underwent UMP using a 3F nephroscope, 7.5F inner sheath, and 11F or 13F outer metallic cannula, which served as the Amplatz sheath. Stone fragmentation and clearance were achieved with holmium laser. No nephrostomy or stent was used routinely. RESULTS: Complete stone fragmentation was achieved in 114 out of 120 patients (95%) using UMP; whereas the remaining 6 were converted into mini-PCNL using a 12.5F nephroscope and 15F Amplatz sheath. The mean operative time was 39.7 ± 15.4 min, and the mean postoperative hospital stay was 22.3 ± 2.2 h. Postoperatively, 6 (5%) patients had residual fragments measuring ≤4 mm. At the 2 weeks follow-up, the stone-free status was >99% (119/120). There were no significant postoperative complications. CONCLUSION: This study shows UMP to be an effective and safe procedure for managing stones up to 20 mm. This procedure offers an attractive alternative to shock wave lithotripsy and retrograde intrarenal surgery for managing small stones.

RESUMO

To study the effectiveness of bilateral subepididymal orchiectomy compared to bilateral simple and subcapsular orchiectomy in terms of androgen ablation, control of disease progression and esthetic superiority. 114 patients of advanced prostatic carcinoma (T3, T4, M1) were randomized to 3 groups- Group A: bilateral simple orchiectomy (38 patients), Group B: bilateral subcapsular orchiectomy (38 patients), & Group C: bilateral subepididymal orchiectomy (38 patients). Serum PSA and serum testosterone values were checked pre-operatively and at 3 months follow-up. Patients' esthetic satisfaction was scored on a quality of life scale of 1-5. In Groups A, B and C, at 3 months the post-operative mean serum testosterone values were 34.7, 38.1 and 36.7 ng/dl (p = 0.0524); and mean serum PSA values were 4.2, 3.9 and 3.4 ng/ml (p = 0.09) respectively, the differences not being statistically significant. On esthetic satisfaction scale the average scores were 1.8, 2.7 and 4.0 respectively, the difference being highly significant (p < 0.0001). Subepididymal orchiectomy maintains esthetic appearance of scrotum and provides superior patient satisfaction as compared to standard total and subcapsular orchiectomy, while achieving equal efficacy. Bilateral sub-epididymal orchiectomy may thus be considered procedure of choice to achieve androgen ablation in advanced prostatic carcinoma.

RESUMO

BACKGROUND AND PURPOSE: Tubeless percutaneous nephrolithotoomy (PCNL), although an accepted technique by now, continues to suffer from two major limitations: The need for postoperative cystoscopy for ureteral stent removal and inability to perform a "second-look" procedure for any residual fragments. We share our experience with a modification of the standard tubeless PCNL technique that allows us to overcome these shortcomings. PATIENTS AND METHODS: A total of 166 patients selected to have PCNL were randomized into two groups of 83 each. In group A (control group), the patients underwent standard PCNL with the insertion of a nephrostomy tube at completion; in group B (intervention group), modified tubeless PCNL was performed with a Double-J (DJ) stent inserted with a tether attached to its proximal end, taken out through the percutaneous tract. The nephrostomy tube in group A was removed postoperatively on the second or third day, whereas those in group B had the stent removed directly by pulling the attached tether within the office setting 10 to 14 days postoperatively. RESULTS: The need for postoperative analgesia was significantly higher in group A compared with group B (mean dose of tramadol needed, 128 mg vs 81.3 mg) (P<0.001). Four patients in group A had postoperative urinary leakage from the nephrostomy site, whereas there were no leaks in patients in group B. Group B patients spent significantly shorter average time in hospital (21.6 hours) compared with group A (54 hours) (P<0.001). Two of the patients in group B needed a second-look procedure, performed by the insertion of a guidewire down the stent, which was pulled out partially by its tether. Presence of the tether in the flank or the process of subsequent removal did not cause any discomfort to any patient. CONCLUSION: The present study demonstrates that tubeless PCNL with a tethered DJ stent overcomes its main drawback, namely, the need for cystoscopy for stent removal, and also allows access to the pelvicaliceal system for second-look nephroscopy.

RESUMO

The role of percutaneous nephrostomy tube for drainage after percutaneous nephrolithotomy (PCNL) procedure has come under scrutiny in recent years. The procedure has been modified to use of small diameter tubes, 'tubeless' PCNL, and even 'totally tubeless' PCNL. A review of the available literature confirms that the chosen method of drainage after PCNL has a bearing upon the post-operative course. It is generally recognized now that small tubes offer benefit in terms of reduced post-operative pain and morbidity. Similarly, nephrostomy-free or 'tubeless' PCNL, using a double-J stent or ureteric catheter as alternative form of drainage, can be used with a favorable outcome in selected patients with the advantage of decreased postoperative pain, analgesia requirement, and hospital stay. Although the tubeless technique has been applied for extended indications as well, the available evidence is insufficient, and needs to be substantiated by prospective randomized trials. In addition, 'totally tubeless' approach has also been shown to be feasible in selected patients.

RESUMO

PURPOSE: To perform a prospective randomized study to evaluate aspiration and sclerotherapy vs. laparoscopic deroofing in the management of symptomatic simple renal cysts. PATIENTS AND METHODS: Forty patients with symptomatic simple renal cysts were randomized to treatment either by ultrasonography-guided aspiration and sclerotherapy (group A-20 patients) or by laparoscopic deroofing (group B-20 patients). Two patients in group A and one patient in group B had a parapelvic cyst. Patients were evaluated by urine analysis, serum creatinine level, coagulation profile, ultrasonography, and CT urography. In group A patients, after aspiration, 1% polidocanol in a volume equivalent to 10% of cyst volume was instilled. In group B patients, laparoscopic deroofing was performed. All patients were followed up by ultrasonography up to 1 year after treatment. RESULTS: In group A, aspiration and sclerotherapy was performed on an outpatient basis, and none of the patients needed postoperative analgesia. Eighteen of 20 patients had complete regression; two of these had parapelvic cyst. Partial regression with relief of pain was noted in one patient, whereas treatment failed in one patient. None of the patients had any significant complication and none required analgesia. All the patients were discharged two hours after the procedure. In group B, laparoscopic deroofing was successfully performed in 19 of 20 patients. Laparoscopic deroofing could not be performed in one patient with parapelvic cyst because of failure of access. The mean analgesic requirement was 285 ± 57.98 (200-400) mg tramadol, and average hospital stay was 2.1 ± 0.32 (2-3) days. CONCLUSION: Percutaneous aspiration and sclerotherapy with polidocanol is an effective, safe, and minimally invasive therapeutic option for symptomatic simple renal cysts, with equal efficacy and lower morbidity and hospital stay in comparison with laparoscopic deroofing.
