Objective: To assess the efficacy of pulsed holmium:YAG laser lithotripsy for ureteral stone therapy. Material and method: Ninety-one patients (70 males and 21 females) with age range 20 – 76 years underwent 93 ureteroscopic procedures for 101 ureteral stones. A preoperative diagnosis was established by ultrasound scanning and intravenous urography. An 8 F rigid Karl-Storz ureteroscope was used for a holmium:YAG laser (OmniPulse MaxTM 80 watt Holmium Laser System Model 1210-VHP, Trimedyne,Inc. Irvine CA, USA) as energy source for laser lithotripsy. The stone localization was mostly at the lower third of the ureter. The mean stone size was 9,6 mm, mean duration of procedure was 48,1 minutes, and the mean hospital stay was 2,1 days. Results: The overall stone clearance rate was 95,6% with the best results for stones in the middle third of the ureter (100%). At follow up we noted two patients with residual stones and two patients with a perforation of the ureteral wall. Conclusion: The Holmium:YAG laser is effective for ureteral stone treatment with a high success rate. Special attention and care should be afforded in impacted ureteral stones.

Introduction: The retrograde approach is a modification that makes the percutaneous cystolitholapaxy (PCCL) a more trendy method, especially in operating rooms with limited facilities. The transurethral approach for bladder calculi lithotripsy by a laser has become popular among urologists. In this study, we investigate the feasibility and safety of retrograde assisted access for PCCL in comparison with transurethral cystolithotripsy by the holmium-YAG laser (Ho: YAG). Methods: According to the type of intervention, the patients were stratified to two matched groups. In the retrograde-assisted percutaneous cystolitholapaxy (RPCCL) group, a Benique was conducted through the urethra into the bladder; palpating the suprapubic region, an about 1.5 cm incision was done over the tip, then an Amplatz sheath was placed over it, treading into the bladder; further cystolitholapaxy was done by a routine order. In transurethral Ho: YAG laser lithotripsy (TULL) via 200 µm fiber vaporize the stone. Results: A total of 124 male patients with the mean age of 50.33±9.64 years and the average stone burden of 3.35±1.07 cm were included in the study. The most common cause of vesical calculi was spinal cord injury. Statistically significant differences were found in terms of the mean operation time in favor of the RPCCL group (P≤0.05) and the mean hospital stay in favor of the TULL group (P≤0.05). The stone-free rate (SFR) was 100% in both methods after a onemonth follow-up. None of the interventions changed to open surgery. There were not any major complications in both methods. Conclusion: RPCCL is a safe and effective method in bladder stone treatment and is applicable in medical centres without Ho: YAG equipment.

Object Chronic subdural hematomas (SDHs) are a local inflammatory process that causes the formation of a granulation tissue often referred to as the external or outer membrane. This membrane has abnormally permeable macrocapillaries. Therefore, exudation from the macrocapillaries in the outer membrane of chronic SDH may play an important role in the enlargement of chronic SDH. In this study the authors investigated the role of exudation in chronic SDH. Methods The authors examined 24 patients (16 men and eight women; age range 38–86 years [mean age 61.4 years]) with 27 chronic SDHs. The clinical status of the patients was evaluated according to the classification described by Markwalder. The diagnosis was established on computed tomography (CT) scans in all cases. The authors also used the Nomura Classification for judging the lesion's appearance on CT scans. Immediately after the diagnosis, all patients were administered 20 mCi (740 mBq) technetium-99m human serum albumin. Four hours later, blood and SDH samples were taken and radioactivity levels were measured in each. The ratio of activity of the samples taken from chronic SDH to the radioactivity of blood was determined as a percentage and defined as the exudation rate. On the follow-up CT scan obtained on postoperative Day 20, subdural collections thicker than 5 mm were determined to be a reaccumulation. Results The correlations between the exudation rate and age of the patients, clinical grades, CT appearances, and amount of reaccumulation were investigated. In this series the average exudation rate was 13.24% (range 2.05–28.88%). The mean exudation rates according to the clinical grades assigned to patients were as follows: Grade 0, 8.67 ± 5.64% (three patients); Grade 1, 5.07 ± 1.43% (eight patients); Grade 2, 17.87 ± 3.73% (seven patients); and Grade 3, 19.65 ± 7.67% (six patients). Exudation rates in patients with Grades 2 and 3 were significantly higher than those in Grades 0 and 1 (p < 0.05). The mean exudation rates according to the lesion's appearance on CT scans were found as follows: hypodense appearance, 6.55 ± 4.52% (eight patients); isodense appearance, 11.07 ± 6.32% (five patients); hyperdense appearance, 19.47 ± 13.61% (three patients); and mixed-density appearance, 17.40 ± 5.80% (nine patients). The differences among the groups were significant (p < 0.05). The average exudation rate was statistically higher in the patients with reaccumulation (16.30 ± 8.16%) than that in the patients without reaccumulation (9.96 ± 6.84%) (p < 0.05). Conclusions The exudation rate in chronic SDH is correlated with a higher clinical grade (Markwalder Grade 2 or 3), mixed-density CT appearance, and reaccumulation. Therefore, exudation from macrocapillaries in the outer membrane of chronic SDH probably plays an important role in the pathophysiology and the growth of chronic SDH.

Background: Several osteotomies have been described for the correction of acetabular dysplasia associated with variable outcomes. The purpose of our study was to evaluate the effect of Dega transiliac osteotomy in radiological correction of acetabular dysplasia by assessing the change in various radiological parameters from preoperative period to postoperative period and at a follow up of two years.Methods: This was a prospective observational study conducted on 35 patients of either sex, in the age range of 18 months to 8 years, presenting to the paediatric orthopaedic OPD, of Artemis Health Institute, Gurgaon, Haryana, India between January 2012 and September 2014 in whom a diagnosis of acetabular dysplasia was made. All the patients underwent Dega transiliac osteotomy and the effectiveness of this osteotomy in the correction of acetabular dysplasia was assessed by measuring various radiological parameters preoperatively, postoperatively, and at a follow up of two years. The various radiological parameters included acetabular index (AI), centre edge angle of wiberg (CEAW), reimer’s extrusion index (REI) and the shenton’s line (SL).Results: In present study sample of 35 cases, 29 had DDH, 4 were secondary to cerebral palsy and 2 had developed dysplasia following septic arthritis of the hip. The sex distribution showed 19 females and 16 male patients. All the patients underwent Dega transiliac osteotomy at a mean age of 42.94±21.68 months. The mean value of AI improved from 42.43±4.77 degrees in preoperative period to 19.86±2.45 degrees at follow up. The mean value of CEAW improved from - 32.49±21.60 degrees in preoperative period to 32.06±5.48 degrees at follow up. The mean value of REI, improved from 91.06±21.43 % in preoperative period to 0.29±1.18 % at follow up. The SL was broken in all the 35 patients preoperatively, while at follow up it was continuous in all the patients. These changes in all the four parameters were statistically highly significant (p value<0.001).Conclusions: Thus results of present study demonstrate that Dega osteotomy is a safe, effective and versatile surgical procedure for the treatment of acetabular dysplasia secondary to DDH and other disorders. Since the majority of the patients included in this study had the diagnosis of DDH, the results of this study are more representative of dysplasia associated with DDH.

AIM: To compare the outcome of an Ex-Press implant and subscleral trabeculectomy (SST) in the management of glaucoma after previous trabeculectomy on a fibrotic bleb. METHODS: This randomized prospective study included 28 eyes from 28 patients (age range: 42-55y) with primary open angle glaucoma (POAG) presented with elevated intraocular pressure (IOP) with fibrotic bleb despite previous SST for more than 4mo. The eyes enrolled in the study were divided into two groups: group I (subjected to Ex-Press implant surgery) and group II [subjected to SST with mitomycin C (MMC)]. The follow-up continued one year after surgery to evaluate IOP, visual acuity (VA), visual field (VF), and postoperative complications. RESULTS: A significant decrease in IOP was found in both groups with a higher reduction in Ex-Press implant surgery with the mean IOP of 14.50 mm Hg (P=0.001), while the SST group recorded the mean IOP of 16.50 mm Hg (P=0.001) after one year. However, the difference between the two groups in terms of the decrease in IOP was insignificant. Fewer postoperative complications were recorded in the Ex-Press implant surgery and more cases requiring further anti-glaucomatous medications were seen in the SST group. Both groups showed stability in terms of VA and VF. CONCLUSION: Ex-Press implant surgery and SST with MMC are two surgical alternatives for controlling IOP in late failure that occurs more than 4mo after previous SST with a fibrotic bleb. However, Ex-Press shunt is a safer surgery with fewer complications.

The aim of the study was to analyze the satisfaction of patients treated with a protocol of six-implant-supported fixed prosthesis (6IFP) throughout 5 years of service. This retrospective study collected the data of all patients who had full-arch rehabilitations using 6IFP and followed them for 5 years. After applying the research inclusion/exclusion strategy, 37 cases were finally included in the study. All the patients had no previous complete dentures because they were partially edentulous, not interested in pursuing complete denture rehabilitation, had immediate dental extractions, implantation used the 2-stage protocol, and there was minor peri-implant socket grafting. Cases with severe bone loss that required extensive grafting were excluded. A total number of 222 implants were placed in the maxillary or mandibular arches in a total of 37 patients. The data presented the satisfaction outcomes concerning mastication, phonetics, and comfort during the first 5 years of the recall plan. The former was achieved based on the clinical record reviews, follow-up visits, and recall phone calls at the preoperative stage as well as annually thereafter. The mean satisfaction rate was 94.5%, with a mean record of 8.21 ± 1.7 out of 10, there was no gender predilection significance, and no age range variation significance was validated. Regarding the smoking status, the t-test score exhibited no significant effect on phonetics and mastication (p = 0.12, p = 0.16, respectively), whereas comfort was found to be significantly affected (p = 0.03). The comfort level was found to be slightly less at the immediate postoperative period among smokers when compared to non-smokers. In conclusion, partially edentulous patients who received the rehabilitation plan of arch dental extractions, six immediate implantations, and delayed prosthetic loading were found to be highly satisfied.

Objectives: We conducted a retrospective study to evaluate the efficacy and outcome of shock wave lithotripsy versus semirigid ureteroscopy in the management of the proximal ureteral stones of diameter exceeding 15 mm. Methods: During the 2009−2014 study period, 147 patients presenting with the proximal ureteral stones exceeding 15 mm in diameter were treated. Both shock wave lithotripsy and ureteroscopy with laser lithotripsy were offered for our patients. A 6/8.9 Fr semirigid ureteroscope was used in conjunction with a holmium:yttrium–aluminum–garnet laser. The stone-free rate was assessed at 2 weeks and 3 months post-treatment. All patients were evaluated for stone-free status, operation time, hospital stay, perioperative complications, and auxiliary procedures. Results: Of the 147 patients who took part in this study, 66 (45%) had undergone shock wave lithotripsy and 81 (55%) underwent ureteroscopy. At the 3-month follow-up, the overall stone-free rate in the shock wave lithotripsy group was 39/66 (59%) compared to 70/81 (86.4%) in the ureteroscopic laser lithotripsy group. Ureteroscopic laser lithotripsy achieved a highly significant stone-free rate ( p = 0.0002), and the mean operative time, auxiliary procedures, and postoperative complication rates were comparable between the two groups. Conclusion: In terms of the management of proximal ureteral stones exceeding 15 mm in diameter, ureteroscopy achieved a greater stone-free rate and is considered the first-line of management. Shock wave lithotripsy achieved lower stone-free rate, and it could be used in selected cases.

Objectives: To find out any changes in renal function in donor following kidney donation. Materials and Methods: A Hospital based prospective study was conducted in the Department of Urology of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from April 2011 to September 2012, Investigations included specific gravity and urinary microalbumin, ultrasonogram of kidneys, serum creatinine, estimated glomerular filtration rate. According to inclusion and exclusion criteria a total of 37 donors were enrolled in this study. Subsequent follow up were taken at the end of three months, six months and nine months. Data were evaluated by Paired t-test, Significance was defined p value<0.05. Results: The age range varied from 25 to 39 years and almost a half (45.9%) of patients had age belonged to 25-30 years and male to female ratio was 1:2.4. The mean baseline specific gravity was 1016.97±8.03, serum creatinine 1.03±0.24. The baseline urinary microalbumin was found nil and subsequent 1st,2nd, and 3rd follow up were also nil. The mean difference of specific gravity, serum creatinine (mg/dl) and GFR estimated by cretainine clearance rate and DPTA were almost consistent between baseline and the subsequent follow-up, no statistical significant (P>0.05) was found between baseline and the subsequent follow-up. Conclusion: Renal function of the remaining kidney in living donors does not significantly change after donor nephrectomy. Bangladesh Journal of Urology, Vol. 19, No. 1, Jan 2016 p.18-22
