| 1 | Contemporary role of multi-tract percutaneous nephrolithotomy in the treatment of complex renal calculi显示文摘Complex renal calculi remain to be a challenge for the treating urologist due to sheer bulk and the technicalities involved.Percutaneous nephrolithotomy(PCNL)remains the treatment modality of choice in dealing with these large and complex stones.The limiting factor in their treatment continues to be the need for using additional tracts or the use of flexible nephroscopy for complete stone clearance.This systematic review focuses on the need for multi-tract PCNL for complex renal calculi.The literature review was performed using PubMed database using the keywords“multiple tract PCNL”or“multiperc”.We identified original articles published on the usage of multiple tracts for stone clearance in renal calculi between January 2000 to October 2018,and the search was restricted to available literature in English language only.Ten studies with n>20 were included for the final analysis.We analyzed the technical efficacy with respect to the number of tracts and stages that were required for stone clearance,outcomes and complications,especially,procedural bleeding and post-procedure infective complications of multiple-tract PCNL for large burden renal stones.Multiperc is found to be safe,feasible and effective for the management of large burden complex renal calculi with respect to stone clearance and morbidity associated with the procedure.It is cost effective and complete stone clearance as a single procedure is higher in comparison to flexible ureteroscopy and shockwave lithotripsy. | Sudharsan Balaji Arvind Ganpule Thomas Herrmann Ravindra Sabnis Mahesh Desai | 2020 | Asian Journal of Urology2020，7，2： | 11 |

| 5 | Primary Malignant Melanoma of Female Urethra:A Case Report and Review of Literature显示文摘We report a very rare case report of female diagnosed with primary malignant melanoma.A 65 years old diabetic elderly postmenopausal female presented with a history of intermittent blood spots on undergarments for few days.Genital examination revealed a single,tan colored,soft chestnut size and polypoidal non ulcerated mass lesion protruding through the urethral meatus.Mass biopsy revealed poorly differentiated epithelial malignancy and immuno-histological analysis revealed positive with HMB 45 and protein S-100 suggestive of melanoma.Metastatic work up for the malignancy was negative.Complete urethrectomy with Mitrofanoff procedure with inguinal lymph node dissection was performed.Histopathological examination was suggestive of malignant melanoma of urethra.Here we discuss the clinicopathological features and management option possible in this scenario. | Shashank Agrawal Tak GR Aditya Parikh Arvind Prakash Ganpule Abhishek Gajendra Singh Ravindra Bhalchandra Sabnis Mahesh Ramanlal Desai | 2019 | Journal of Oncology Research2019，1，3： | 0 |
| 6 | Single-use flexible ureteroscopes: Comparative in vitro analysis of four scopes显示文摘Objective:Single-use flexible ureteroscopes(fURSs)have recently been introduced by different companies.Goal of this in-vitro study was to compare four fURSs.Methods:We performed in vitro analysis of Uscope 7.5 Fr and Uscope 9.5 Fr(Pusen Ltd.,Zhuhai,China),LithoVue 9.5 Fr(LithoVue,Boston Scientific,MA,USA),and Indoscope 9.5 Fr(Bioradmedisys,Pune,India).Optical characteristics(image resolution,color representation,and luminosity)were compared at various distances of 10 mm,20 mm,and 50 mm.Deflection and irrigation were evaluated with and without accessories.Results:Color perception was comparable for all scopes at 10 mm(p<0.05),while Lithovue 9.5 Fr was comparable with Indoscope 9.5 Fr at the distances of 20 mm and 50 mm.Both scopes were statistically better than both Uscopes at the distances of 20 mm and 50 mm.Image resolution powers were comparable amongst all fURSs at the distances of 10 mm and 20 mm(3.56 line pairs per millimeter[lp/mm]).However,Indoscope(3.56 lp/mm)was superior to LithoVue and Uscope scopes(3.17 lp/mm)at the distance of 50 mm.Luminosity at the distance of 10 mm was comparable for LithoVue and Uscope 9.5 Fr.However,at the distances of 20 mm and 50 mm,LithoVue had the highest luminosity while Uscope 7.5 Fr had the lowest one.Indoscope had lower luminosity than other 9.5 Fr scopes at all distances.With empty working channel and 200 mm laser fiber,Indoscope had the maximum deflection(285).With basket,Uscope 7.5 Fr had the maximum loss of deflection(30)while Indoscope had no deflection loss.With empty working channel,all scopes had comparable irrigation flow rates in both deflected and undeflected state.Similarly,with 200 mm laser or basket,irrigation flow rates were comparable in all scopes.Conclusion:Color representation was equivalent for Indoscope and LithoVue,while being better than Uscope 7.5 Fr and Uscope 9.5 Fr.Image resolution was comparable in all scopes at the distances of 10 mm and 20 mm.Beyond the distance of 10 mm,luminosity of LithoVue was the highest and that of Uscope 7.5 Fr was the lowest.Deflection loss was the minimum with Indoscope and the maximum with 7.5 Fr Uscope.Under all scenarios,irrigation flow rates were comparable in all scopes. | Abhijit Patil Shashank Agrawal Rohan Batra Abhishek Singh Arvind Ganpule Ravindra Sabnis Mahesh Desai | 2023 | Asian Journal of Urology2023，10，1： | 0 |
| 7 | The clinical outcomes of laser with suction device in mini-percutaneous nephrolithotomy显示文摘Objective:To evaluate the safety,efficacy and feasibility of laser with suction device in mini-percutaneous nephrolithotomy(mini-PCNL).Methods:A retrospective study was conducted including 200 patients who underwent mini-PCNL for renal stones.All patients underwent PCNL using Electro-Medical Systems laser.In addition to the laser in 100 patients,a suction device was used(laser with suction[LWS]).In the other 100,suction device was not used(laser with no additional suction[LOS]).Mini-PCNL was performed using standard technique and Karl Storz minimally invasive PCNL-medium system was used.Primary end point was stone clearance.Results:Both the groups were comparable in terms of demographic data.Mean stone size was 15.24±5.90 mm and 16.16±5.53 mm in LWS and LOS,respectively.Mean Hounsfield unit of stone was 1285.64 and 1206.79 in LWS and LOS,respectively.Operative time was less in LWS group(56.89±19.65 min)as compared to LOS(62.01±28.81 min).At one-month follow-up,radiological complete clearance was 96%in LWS and 92%in LOS.On subgroup analysis of stones larger than 18 mm,the clearance rate was in favour of LWS(85.7%vs.100%)and also the need for nephrostomy placement was less in LWS group.Conclusions:LWS device is safe and efficacious when used with mini-PCNL.For stones greater than 18 mm,it has a better stone free rate as compared to using no suction. | Abhishek Gajendra Singh Sundaram Palaniappan Shrikant Jai Gopal Tak Arvind Ganpule Ravindra Sabnis Mahesh Desai | 2022 | Asian Journal of Urology2022，9，1： | 0 |
