Objective: To compare long-term outcomes of buccal mucosa graft (BMG) augmentation urethroplasty for long segment bulbar urethral strictures done by placing the graft ventrally, dorso-laterally and dorsally. Material and methods:We conducted a single institution retrospective study on 112 who underwent BMG augmentation urethroplasty for non-traumatic bulbar urethral strictures between January 2005 to December 2014. The cases were divided into three groups based on the site of placement of BMG graft i.e. (a) Ventral (n=44), (b) Dorso-lateral (n=48) and (c) Dorsal (n=20). Follow-up period was from one year to five years. Patients with failed outcomes underwent urethroscopy or retrograde urethrogram to note the site of recurrence of stricture. Results:Out of 112 cases 91 (81%) were successful and 21 (19%) failed. The success rates for ventral, dorsolateral and dorsal BMG augmentation procedures were 89%, 79% and 70%, respectively (p= 0.18). Among 21 failed cases, 12 cases (57%) had stricture at proximal anastomotic site, 4 cases (19%) at graft and 5 cases (24%) at distal anastomotic site (p= 0.01). Conclusion:The overall success rate for BMG augmentation urethroplasty is equal for all techniques. Ventral onlay urethroplasty provides better exposure of proximal anastomotic site thus it is associated with minimum proximal anastomotic site recurrence rates. Patients with extensive spongiofibrosis and long segment strictures had higher rates of failure.
In this paper we have proposed face recognition door lock system using raspberry pi for enhancing security purpose. Implementation of the device is for monitoring whether any unknown person is entering from the door. In order to get accurate and clear picture of an victim we have proposed Haar Cascade method for detecting face. As soon as the person enters near the door, pi camera captures the image of that person and face detection process is done then if it matches with images available in database then the door is unlocked otherwise a message with the picture of a person will be sent to the registered mobile through LAN network. The main motto of this project is to utilization of sensor with the combination of embedded equipment for the door opening systems. The main purpose of this system is to provide best security for home and office by using face recognition technique.
INTRODUCTIONThe urethra is traditionally divided into anterior and posterior parts. The anterior part is surrounded by the corpus spongiosum. It includes the bulbar urethra, which is enclosed by the bulbospongiosus muscle and the penile urethra that runs from the distal margin of the bulbospongiosus to the fossa navicularis and external ABSTRACT Background: Urethral stricture is an acquired permanent narrowing of the urethra impeding the flow of urine during micturition. It is one of the oldest urological diseases, and its treatment remains a challenge for urologists. Urethral stricture disease affects about 300 per 100,000 men. Most common causes are trauma and infections in developing countries and idiopathic in developed countries. Treatment options for short bulbar urethral strictures include dilatation, direct visual internal urethrotomy and anastomotic urethroplasty. Excision and end to end anastomosis (anastomotic urethroplasty) for short bulbo-membranous urethral strictures and buccal mucosal graft gives excellent long term results with reduced recurrence rate. Methods: Sixty-three patients who had undergone anastomotic urethroplasty from 2013 to 2016 at Government Medical College and Superspeciality Hospital, Nagpur, Maharashtra, India Department of Urology were included in the study. For strictures less than 2cm, excision of stricture and anastomosis done, while for stricture more than 2cm buccal mucosal grafting done over 16 F Foleys catheter. Postoperative follow up done up to 1 year. Results: The total number of patients included is 63 and study conducted between January 2013 to December 2016. End to end urethroplasty was done in 41 patients and had mean duration of surgery of about 120 minutes, while buccal mucosal grafting was done in 22 patients. Age ranges from 14 to 78 years with highest incidence of stricture was seen after 5 th decade of life, mainly due to iatrogenic causes of previous instrumentation and post TURP surgery. Strictures in younger adults are mainly as a result of trauma by fall astride injury and pelvic fractures and seen during 3 rd and 4 th decade of life. Most common length of stricture observed was 1-2cm in about 65.07% and mainly occurred due to post urethral procedures. Long strictures more than 2cm were mainly because of trauma in about 35%. Seven patients had recurrence in follow up, out of which 2 managed conservatively by repeated dilatation and 5 patients needed reoperation. Conclusions:The present results suggest that in patients with strictures too long to be excised and re-anastomosed a tension-free buccal mucosal graft provides better results. However, in patients with short strictures, in whom a completely tension-free anastomosis can be achieved, direct end-to-end anastomosis remains good option.
Each building requirements a table to survive a system of resisting major forces caused by wind speed or heavy earthquakes. One of the finest arrangement is outrigger. Outriggers of structural elements hold the arrangement of earthquake loads together. When the difficulty of the tallness of the structure is greater than before they turn out to be larger as well as the addition of tempting additions to oppose systems such as truss consists of belt and outriggers is essential. consumption of structural regulation adds structural power by connecting the main building with the remote colony and making the whole body function as a single unit in opposition to the trouble. The present review articles deals with the research based on the Outrigger Wall and Wall Belt Supported System by different researchers. The observation includes based on the reviews in that inputs of Outrigger Wall andWall Belt increase the performance of building in terms of stability, stiffness, strength & cost.
Background: Urogenital fistula is an abnormal fistulous communication that occurs between the bladder and cervix or uterus; between the ureter and vagina, uterus, or cervix; and between the urethra and vagina. Most cases in developing countries are of obstetric etiology, resulting from prolonged neglected obstructed labour, and around 1–2 per 1000 deliveries may be affected. The majority of UGFs in developed countries are a consequence of gynecological surgery, mainly hysterectomies. Present study focuses on the various presentations and the different modalities of surgeries done for cases of urogenital fistulas at our institute.Methods: A total 19 cases of urogenital fistula were studied in detail as per proforma. Two patients were operated on emergency basis because of early presentation in postoperative period. For others a pre-operative waiting period of 3-6 months was followed after development of fistula. During this period initially bilateral DJ stenting was tried in all patients, in hope of spontaneous closure of fistulas. Two patients whose fistulas closed spontaneously are not subjected to surgery. Rest all cases were managed surgically by standard surgical procedures.Results: Study was conducted between, February 2015 to February 2017. A total 19 patients studied. In 2 patients, fistula healed spontaneously while in 17 patients, surgery was needed. Most common age group affected is 2nd decade of life about 47.36%. In our study gynecological surgeries predominate with 57.89% followed by obstetric cases in 26.31%. Most of patients presented with continues dribbling of urine through vagina with normal voiding pattern in about 78.94% of cases. Overall transabdominal procedures had nearly 100% success rate, mainly because of better dissection, visualization and use of vascularized graft which prevents recurrence. 1 recurrence was seen in transvesical extraperitoneal approach because of undiagnosed another fistulous tract. Ureteric reimplantation was 100% successful in ureterogenital fistulas. Vaginal approach with use of Mortius flap had 75% success rate with 1 recurrence because of flap necrosis. Mean duration of surgery was 120 minutes and mean hospital stay was 8 days..Conclusions: Urogenital fistulas are the most distressing complications of obstetric and gynecological surgeries. Obstetric causes predominate in developing countries while gynecological surgeries predominate in developed countries. Despite the good results of surgical repair, attempt should be focused on the prevention of VVF.
