A Prospective Randomized Study Comparing Percutaneous Nephrolithotomy under Combined Spinal-Epidural Anesthesia with Percutaneous Nephrolithotomy under General Anesthesia

Objective: A prospective randomized study was executed to compare the surgical parameters and stone clearance in patients who underwent percutaneous nephrolithotomy (PNL) under combined spinal-epidural anesthesia (CSEA) versus those who underwent PNL under general anesthesia (GA). Methods: Between January 2008 to December 2009, 64 patients with renal calculi were randomized into 2 groups and evaluated for the purpose of this study. Group 1 consisted of patients who underwent PNL under CSEA and Group 2 consisted of patients who underwent PNL under GA. The operative time, stone clearance rate, visual pain analog score, mean analgesic dose and mean hospital stay were compared amongst other parameters. Results: The difference between visual pain analog score after the operation and the dose of analgesic requirement was significant on statistical analysis between both groups. Conclusion: PNL under CSEA is as effective and safe as PNL under GA. Patients who undergo PNL under CESA require lesser analgesic dose and have a shorter hospital stay.

Prospective evaluation of complications using the modified Clavien grading system, and of success rates of percutaneous nephrolithotomy using Guy's Stone Score: A single-center experience

Introduction and Objectives: To prospectively document the perioperative complications of percutaneous nephrolithotomy (PCNL) using the modified Clavien grading system. Evaluation of complications and clearance rates according to stone complexity using the validated Guys Stone Score (GSS) was also done. Materials and Methods: A total of 221 renal units underwent 278 PCNL procedures at a urology resident training center between September 2010 and September 2011 and data were recorded prospectively in our registry. Patients with co-morbidities like diabetes, renal failure, hypertension and cardiopulmonary diseases were excluded. Stone complexity was classified according to the GSS while peri-operative complications were recorded using the modified Clavien grading system. Results: Two hundred and forty-five complications were encountered in 278 PCNL procedures involving 116 renal units (41.72%). Complications of Grades 1, 2, 3a, 3b, 4a, 4b and 5 were seen in 52 (18.7%), 122 (43.8%), 42 (15.1%), 18 (6.4%), 6 (2.1%), 4 (1.4%) and 1 (0.3%) renal units respectively. There were 68, 98, 50 and 5 renal units in GSS I, II, III and IV groups, respectively. All grades of complications were more common in GSS III and IV (P<0.05). For GSS I, II, III and IV 100%, 74%, 56% and 0% of renal units, respectively, were stone-free after one session and 0%, 24%, 44% and 60% respectively needed two sessions to be stone-free. Conclusion: Although the complication rates were higher most were of low grade and self-limiting. Complications were significantly more common with higher GSS and the GSS effectively predicted stone-free rates.

Donor site morbidity in oral mucosa graft urethroplasty: implications of tobacco consumption

BackgroundThe purpose of this prospective study was to evaluate the donor site morbidity in patients who have undergone oral mucosa graft urethroplasty for stricture of the urethra. The impact of smoking and oral consumption of tobacco and/or paan masala on the donor site was also assessed. This study is probably the first of its kind where the affect of smoking, paan masala and tobacco chewing on the donor site morbidity has been documented.MethodsForty-eight patients suffering from stricture of the urethra underwent oral mucosa graft urethroplasty between July 2005 and December 2007. The patients were divided into two groups (users or non-users) based on tobacco consumption and oral hygiene. The donor site was evaluated at frequent intervals for pain, swelling, numbness, bleeding, salivation and tightness of mouth.ResultsDonor site morbidity was more in users with poor oral hygiene. Pain scores were higher amongst the users and the morbidity persisted longer in the users compared to non-users with good oral hygiene.ConclusionPatients who consume tobacco and have poor oral hygiene should be warned regarding poorer outcomes after oral mucosa graft urethroplasty.

Reconstructive Surgery for Penoscrotal Filarial Lymphedema: A Decade of Experience and Follow-up

OBJECTIVES To present our experience of reconstructive surgery in patients with penoscrotal filarial lymphedema. METHODS From January 2000 to December 2009, we treated 48 patients with penile and penoscrotal filarial lymphedema using reconstructive surgery. Isolated penile involvement was seen in 14 patients, and 34 patients had penoscrotal involvement. All the patients had taken multiple courses of antifilarial drug before surgery. For isolated penile involvement, the diseased penile skin was excised and covered with a split-thickness skin graft. In some patients, the inner prepucial skin was preserved and used to cover the penile shaft. For those with penoscrotal involvement, scrotoplasty was performed, after excising the diseased scrotal skin and underlying soft tissue, while sparing the testes and spermatic cords. RESULTS The mean patient age was 38 years (range 25-52), and the median follow-up time was 48 months (range 10-120). All 48 patients reported a satisfactory cosmetic appearance after the procedure and noted improvement in their ability to void while standing. Also, all of them could ambulate better and resumed sexual activity. Local groin infection was present in 12 patients; all were cured after proper management. CONCLUSIONS In filarial lymphedema of penis and/or scrotum, excision of the diseased tissue and covering with a split-thickness skin graft provided good results. If the inner prepucial skin is healthy, it should be used to cover the distal penile shaft. If the scrotum is involved, scrotoplasty with lateral and posterior mobilized flaps provides satisfactory results.

Antiplatelet drugs and the perioperative period: What every urologist needs to know.

Antiplatelet agents like aspirin and clopidogrel are widely used for indications ranging from primary and secondary prevention of myocardial infarction or stroke to prevention of coronary stent thrombosis after percutaneous coronary interventions. When patients receiving antiplatelet drugs are scheduled for surgery, urologists commonly advise routine periprocedural withdrawal of these drugs to decrease the hemorrhagic risks that may be associated if such therapy is continued in the perioperative period. This approach may be inappropriate as stopping antiplatelet drugs often exposes the patient to a more serious risk, i.e. the risk of developing an arterial thrombosis with its potentially fatal consequences. Moreover, it has been seen that the increase in perioperative bleeding if such drugs are continued is usually of a quantitative nature and does not shift the bleeding complication to a higher risk quality. We, in this mini review, look at the physiological role and pathological implications of platelets, commonly used antiplatelet therapy and how continuation or discontinuation of such therapy in the perioperative period affects the hemorrhagic and thrombotic risks, respectively. Literature on the subject between 1985 and 2008 is reviewed. The consensus that seems to have emerged is that the policy of routine discontinuation of antiplatelet drugs in the perioperative period must be discouraged and risk stratification must be employed while making decisions regarding continuation or temporary discontinuation of antiplatelet therapy. Although antiplatelet drugs may be discontinued in patients at a low risk for an arterial thrombotic event, they must be continued in patients where the risks of bleeding and complications related to excessive bleeding are less than the risks of developing arterial thrombosis.

Squamous Cell Carcinoma of the Kidney â Rarity Redefined: Case Series with Review of Literature

Squamous cell carcinoma of the renal pelvis and ureter is a rare malignancy, having an incidence of 6% to 15% (of all urothelial tumors). Few cases of primary squamous cell carcinoma of kidney have been reported in the world literature. The insidious onset of symptom and lack of any pathognomonic sign, leads to delay in the diagnosis and subsequent treatment, resulting in grave prognosis for these patients. Herein, we report 5 cases (three males and two females) of advanced primary squamous cell carcinoma of kidney that were treated at our centre during the last 6 years. The average age was 57 years (range 50-65 years). Three of the patients had history of long standing renal calculus disease while 3 had history of smoking and 1 patient had history of analgesic abuse. These cases were unique because in few of them; all the calyces were involved by the tumor - a field change type of pattern normally seen in transitional cell carcinoma of the kidney. In one patient, thrombus of the inferior vena cava was also present along with infi ltration of the duodenum by the tumor. Despite prompt nephroureterectomy, 4 out of 5 patients died within 6 months of treatment. Only one patient was surviving at 5 months of follow up. Nephrectomy with or without ureterectomy is the treatment of choice in patients suffering from squamous cell carcinoma of the kidney. There is lack of evidence of survival benefi ts of chemo-radiation following surgery but is advocated by some with the hope that it might increase survival. Biopsy from the renal pelvis or calyceal wall is advocated at the time of stone removal in patients having long-standing history of large renal calculi or staghorn calculus since such patients are capable of harboring occult or overt malignancy.

Bilateral testicular gangrene: does it occur in Fournier's gangrene?

Fournier’s gangrene (FG) is an infective necrotizing fascitis of the perineum, genital and perianal area leading to gangrene of the overlying skin and subcutaneous tissue. Testis and epididymis tend to be spared. We report a case of a young male with bilateral gangrene of the testis.

Harvesting buccal mucosa graft under local infiltration analgesia--mitigating need for general anesthesia.

For buccal mucosal graft urethroplasty, nasal or oral endotracheal intubation anesthesia is used for harvesting the graft from the oral cavity. A technique of graft harvesting under local anesthesia using 2% lidocaine solution with adrenaline (1:200,000) is described. This method requires a cooperative patient but saves the morbidity of general anesthesia.

Factors affecting response to medical management in patients of filarial chyluria: A prospective study

Introduction: Filarial chyluria is a common problem in filarial endemic countries. Its management begins with medical therapy but some patients progress to require surgery. The present study aimed to determine factors affecting response to medical management in patients of filarial chyluria. Materials and Methods: This prospective study conducted between August 2008 and November 2012, included conservatively managed patients of chyluria. Demographic profile, clinical presentation, treatment history and urinary triglycerides (TGs) and cholesterol levels at baseline were compared between the responders and non-responders. Apart from the clinical grade of chyluria, hematuria was evaluated as an independent risk factor. Results: Out of the 222 patients (mean age, 37.99 ± 13.29 years, 129 males), 31 patients failed to respond while 35 had a recurrence after initial response; the overall success rate being 70.3% at a mean follow-up of 25 months. No difference was observed in demographics, clinical presentation, presence of hematuria, disease duration and mean urinary TGs loss between responders and non-responders. On multivariate analysis, patients with treatment failure were found to have a higher-grade disease (14.3% Grade-I, 36.6% Grades-II and 60% Grade-III), higher number of pretreatment courses (1.59 ± 1.08 vs. 1.02 ± 0.79) and heavier cholesterol (26.54 ± 23.46 vs. 8.81 ± 8.55 mg/dl) loss at baseline compared with responders (P < 0.05). Conclusion: Conservative management has a success rate in excess of 70%, not affected by the disease chronicity, previous episodes and recurrent nature. However, higher-grade disease, extensive pre-treatment with drugs and higher urinary cholesterol loss at baseline are the predictors of poor response. Hematuria is not an independent poor risk factor for conservative management.

Outcome of Simultaneous Transurethral Resection of Bladder Tumor and Transurethral Resection of the Prostate in Comparison with the Procedures in Two Separate Sittings in Patients with Bladder Tumor and Urodynamically Proven Bladder Outflow Obstruction

BACKGROUND AND PURPOSE A prospective randomized study was undertaken wherein transurethral resection of bladder tumor (TURBT) was performed along with transurethral resection of the prostate (TURP) in the same sitting (group A) in patients with bladder tumor and urodynamically proven bladder outflow obstruction. The outcome (recurrence and progression of superficial transitional cell carcinoma) was compared with patients who underwent TURBT and TURP in two separate sittings (group B) approximately 6 months apart. PATIENTS AND METHODS Between January 2002 and December 2007, 48 patients were randomized for this study. The inclusion and exclusion criteria are described below. The patients were followed up according to standard protocols. The two groups were compared for the recurrence and progression of the bladder tumor. RESULTS Mean age in both the groups were similar (group A = 56.06 +/- 4.45 years, group B = 57.36 +/- 3.65 years). The mean duration of follow-up was also similar between the two groups (group A, 35.71 +/- 12.8 months; group B, 37.55 +/- 14.12 months; P > 0.05). In group A, 12 (50%) patients had recurrence, while in group B, 11 (42.85%) patients had recurrence. The differences in recurrence, mean elapsed time to recurrence, and progression of tumor between the two groups were statistically insignificant. CONCLUSION TURBT and TURP can be performed simultaneously without any increased risk of recurrence and progression of tumor, if performed in a properly selected group of patients.
