Introduction:The correction of fossa navicularis strictures poses a distinct reconstructive challenge as it requires attention to cosmesis, in addition to urethral patency. Different graft and flap based repairs have been described with variable success rates. However, the ideal management remains unclear. The feasibility and efficacy of a single stage ventral onlay buccal mucosa graft urethroplasty (VOBMGU) for navicular fossa strictures (NFS) was evaluated in the present study.Subjects and Methods:All patients with NFS attending urology out-patient department from March, 2009 onward accepting VOBMGU were evaluated prospectively. Patients with minimum 1 year of follow-up were included for analysis. The technique involves opening the diseased stenosed meatus ventrally up to the corona. The diseased mucosa is excised leaving a midline strip of native urethral mucosa on the dorsal side. The buccal mucosal graft (BMG) is fixed on either side of this strip over a 24 Fr. silicone catheter. The glans wings are apposed in midline taking anchoring bites on the mucosal graft ventrally. Post-operatively patients were reviewed at 1, 3, 6 and 12 months and annually thereafter. Cosmetic acceptance and splaying of the urinary stream was assessed with individual questionnaires.Results:A total of six patients underwent VOBMGU. Average flow rate at 3 months post-operatively was 12 ml/s. The end result was cosmetically highly acceptable. There was no fistula in any of the cases. With a median follow-up of 37 months, only one patient had a recurrence of stricture in a proximal site.Conclusions:VOBMGU is a viable technique for reconstruction of NFS with promising short term results. However, long-term follow-up is necessary.
CT guided FNAC is a well established method in the cytological diagnosis of pulmonary lesion. Aim: Aim of our study is to evaluate the pathological spectrum of disease in lump through CT guided FNAC. Material & method: 69 causes were evaluated retrospectively for a period of 4 yrs. Result: out of 69 cases 52.1% were male. Mean age was 54. 34 years. 65.2% having malignant lesion & 34.7% have benign. Adeno CA was the predominant malignant tumour. Conclusion: CT guided FNAC can diagnose pulmonary lesion fairly accurately leading to less morbidity & mortality as treatment can be started early.
Context:Bombay blood group although rare is found to be more prevalent in the Western and Southern states of India, believed to be associated with consanguineous marriage.Aims:To estimate the prevalence of the Bombay blood group (Oh) in the urban population of Puducherry. To find the effect of urbanization on consanguineous marriage and to establish whether consanguinity plays a part in the prevalence of Oh group. To compare Oh group prevalence with that of other neighboring states, where population is not predominantly urban.Settings and Design:This is a descriptive study in a tertiary care hospital in Puducherry, over a period of 6 years.Materials and Methods:All blood samples showing ‘O’ group were tested with anti-H lectin. Specialized tests like Adsorption Elution Technique, inhibition assay for determination of secretor status were performed on Oh positive cases. Any history of consanguineous marriage was recorded.Statistical Analysis Used:All variables were categorical variable and percentage and proportions were calculated manually.Results:Analysis of the results of 35,497 study subjects showed that the most common group was ‘O’ group constituting 14,164 (39.90%) of subjects. Only three “Oh” that is, Bombay phenotype (0.008%) were detected. Consanguinity was observed in two cases (66.66%).Conclusions:This study shows the prevalence of Bombay blood group representing the urban population of Puducherry, to be high (0.008%) and associated with consanguineous marriage (66.66%). Thus, consanguinity is still an important risk factor present, even in an urban population in Southern India.
Introduction:A precise puncture of the renal collecting system is the most essential step for percutaneous nephrolithotomy (PCNL). There are many techniques describing this crucial first step in PCNL including the bull's eye technique, triangulation technique, free-hand technique, and gradual descensus technique. We describe a novel puncture guide to assist accurate percutaneous needle placement during bull's eye technique.Methods:The mini access guide (MAG) stabilizes the initial puncture needle by mounting it on an adjustable multidirectional carrier fixed to the patient's skin, which aids in achieving the “bull's eye” puncture. It also avoids a direct fluoroscopic exposure of the urologist's hand during the puncture. Sixty consecutive patients with solitary renal calculus were randomized to traditional hand versus MAG puncture during bull's eye technique of puncture and the fluoroscopy time was assessed.Results:The median fluoroscopy screening time for traditional free-hand bull's eye and MAG-guided bull's eye puncture (fluoroscopic screening time for puncture) was 55 versus 21 s (P = 0.001) and the median time to puncture was 80 versus 55 s (P = 0.052), respectively. Novice residents also learned puncture technique faster with MAG on simulator.Conclusion:The MAG is a simple, portable, cheap, and novel assistant to achieve successful PCNL puncture. It would be of great help for novices to establish access during their learning phase of PCNL. It would also be an asset toward significantly decreasing the radiation dose during PCNL access.
