Background: The main aim of hypospadias repair is to preserve the urethral plate whenever possible. This study was undertaken to compare the outcome of repair of severe hypospadias with moderate chordee by single-stage Snodgrass with two-stage repair with dermal graft corporoplasty. Methods: This prospective cross-section study was done in the Department of Urology, Chalmida Anand Rao Institute of Medical Sciences, Bommakal, Karimnagar. The selection of the patients the type of surgery was based on the type of case. A total of n=31 patients were operated for severe hypospadias out of which n=14 single surgeries and n=17 two-staged surgeries were performed. Results: N=25 patients were found with a moderate degree of chordee. No complications were found in n=11(78.57%) in single-stage repairs and two-stage repairs n=15(88.23%) were without complications the p values were found to be 0.012 which is significant. HOSE scores Erection correction was better in two staged surgeries as compared to single-stage repairs with p values <0.001 which is considered significant. Conclusion: We can conclude that the repair of severe hypospadias with moderate chordee by two-staged repair showed better outcomes as compared to single-stage repair. The incidence of postoperative complications is also lesser with two-staged repairs. However, the choice of the procedure must be based on the type of hypospadias, choice of patients and economical constraints.

Objectives. To determine the demographics and analyze the management and factors influencing the postoperative complications of hypospadias repair. Settings. Hayatabad Medical Complex Peshawar, Pakistan, from January 2007 to December 2011. Material and Methods. All male patients presenting with hypospadias irrespective of their ages were included in the study. The data were acquired from the hospital’s database and analyzed with Statistical Package for Social Sciences (SPSS). Results. A total of 428 patients with mean age of 8.12 ± 5.04 SD presented for hypospadias repair. Midpenile hypospadias were the most common. Chordee, meatal abnormalities, cryptorchidism, and inguinal hernias were observed in 74.3%, 9.6%, 2.8%, and 2.1% cases, respectively. Two-stage (Bracka) and TIP (tubularized incised urethral plate) repairs were performed in 76.2% and 20.8% of cases, respectively. The most common complications were edema and urethrocutaneous fistula (UCF). The complications were significantly lower in the hands of specialists than residents (P-value = 0.0086). The two-stage hypospadias repair resulted in higher complications frequency than single-stage repair (P value = 0.0001). Conclusion. Hypospadias surgery has a long learning curve because it requires a great deal of temperament, surgical skill and acquaintance with magnifications. Single-stage repair should be encouraged wherever applicable due to its lower postoperative complications.

Background: Hypospadias is a common congenital anomaly affecting the penis, two-stage repair becoming more interesting in era of tubularized –incised urethral plate (TIP). Functional outcome of hypospadias repair either single or two stage is as important as cosmetic outcome. In contemporary series , structured scoring systems (Hypospadias Objective Scoring Evaluation-HOSE and Pediatric Penile Perception Scoring -PPPS), evaluation of photographs and uroflowmetry, were used to assess results of hypospadias repair. Objectives: We have assessed outcomes of two-stage hypospadias repair using Hypospadias Objective Scoring Evaluation(HOSE) and uroflowmetry. Material and Methods: Over a period of eight years, from January 1997 to December 2004, One hundred and twenty six hypospadias patients were treated, ninety of them had two-stage repair and36 single-stage repairs. The HOSE questionnaire and uroflowmetry were obtained to evaluate the long term outcome of two –stage hypospadias repair. Results: The age at time of assessment ranged from 8 to 23 year-old, with mean follow up of 39.78months. Thrifty five patients had proximal hypospadias and 20 had distal varieties of hypospadias. Operations performed were 37 Bracka?s and 18 Byar?s procedures. Of the 55 patients had complete two stage hypospadias repair and agree to participate in the study , Nineteen patients had acceptable HOSE and 36 had non-acceptable score. Uroflow rates of 43 subjects were below the fifth centile in three patients ,equivocal (between 5th and 25th centile ) in four patients and above 25th centile in 36 subjects. Conclusion: Two –stage repair is a suitable technique for all types of hypospadias with versatile outcomes. HOSE and uroflowmetry are simple, easy, non invasive and non expensive tools to assess long term outcomes objectively.

<p class="abstract"><strong>Background:</strong> Open fracture both bone leg is a common fracture present in orthopaedic causality. Treatment consists of I. V. antibiotics, debridement and external fixator. Judicious selection of the patients on basis of Gustilio and Anderson classification leads to external fixator as a definitive and single stage procedure with dynamization. It reduces the risk of infection at time of definitive procedure and number of hospital stay and surgery.</p><p class="abstract"><strong>Methods:</strong> In school of medical sciences and research, We treated 68 patients with open both bone fracture (Gustilio and Anderson type 2 and 3b) with debridement and external fixator. All patients underwent dynamization depending upon fracture pattern. Majority of our cases were road traffic accident involving male. Average duration of union was 22 to 26 weeks. There was no need for any major plastic surgery procedure. Removal of external fixator and Patellar tendon brace (PTB) was given for the period of 4 to 6 weeks at the time of clinical and radiological union.<strong></strong></p><p class="abstract"><strong>Results:</strong> Eighty eight percent of our cases united well. This reduces the burden of secondary definitive procedure, infection and cost of treatment. So careful selection of the patients and dynamization of external fixator hold the place for definitive surgical option for open both bone fractures.</p><p><strong>Conclusions:</strong> External fixator is simple effective surgical procedure for open fractures both bone leg. Staged dynamization of external fixator add in the better union with functional outcome and cost effective. </p>

The Stability

The stability and operational performance of single stage digestion with and without liquor recycle and two stage digestion were assessed using a mixture of paper and wood as the digestion substrate. Attempts to maintain stable digestion in both single stage reactors were unsuccessful due to the inherently low natural buffering capacity exhibited; this resulted in a rapid souring of the reactor due to unbuffered volatile fatty acid (VFA) accumulation. The use of lime to control pH was unsatisfactory due to interference with the carbonate/bicarbonate equilibrium resulting in wide oscillations in the control parameter. The two stage system overcame the pH stability problems allowing stable operation for a period of 200 days without any requirement for pH control; this was attributed to the rapid flushing of VFA from the first stage reactor into the second stage, where efficient conversion to methane was established. Reactor performance was judged to be satisfactory with the breakdown of 53% of influent volatile solids. It was concluded that the reactor configuration of the two stage system offers the potential for the treatment of cellulosic wastes with a sub-optimal carbon to nitrogen ratio for conventional digestion.

The two-stage ejector has been suggested to replace the single-stage ejector geometrical configuration better to utilize the discharge flow’s redundant momentum to induce secondary flow. In this study, the one-dimensional gas dynamic constant rate of momentum change theory has been utilized to model a two-stage ejector along with a single-stage ejector. The proposed theory has been utilized in the computation of geometry and flow parameters of both the ejectors. The commercial computational fluid dynamics tool ANSYS-Fluent 14.0 has been utilized to predict performance and visualize the flow. The performance in terms of entrainment ratio has been compared under on- design and off-design conditions. The result shows that the two-stage ejector configuration has improved (≈57%) entrainment capacity than the single-stage ejector under the on-design condition.
