Publication Comparison between Simple and Classical Techniques to Create Closed Pneumoperitoneum(Kathmandu University, 2021) Gharti, BB; Shrestha, PM; Shrestha, A; Basnet, RB; Shah, C; Adhikari, BABSTRACT Background Closed method of pneumoperitoneum using Veress needle is an established technique. Classical closed technique is popular. Simple technique is a modified closed technique. Objective To compare the classical and simple techniques of closed pneumoperitoneum. Method This study was conducted in the department of urology, Bir hospital from August 1st 2019 to March 30th 2021. Total 114 patients were randomized into simple and classical technique of creating closed pneumoperitoneum. Time taken for creation of pneumoperitoneum, complications and failure of creating pneumoperitoneum in each group noted and analyzed. Chi square test, Fischer exact test and student t test were used and p < 0.05 considered significant. Result Among 114 patients, 61 in simple and 53 in classical technique allocated. In simple technique, mean age was 42.98±18.21 years, BMI was 21.84±2.57 kg/m2, mean time for pneumoperitoneum creation was 108.07±21.14 seconds. In classical technique, mean age was 40.15±17.58 years, BMI was 21.94±2.54 (kg/m2), mean time for pneumoperitoneum creation was 189.70±32.21 seconds. Mean time was less in simple technique than classical technique (p < 0.001). Complication rate observed was 6% in each technique (p=0.797) with cumulative rate of 10%. Omental injury was seen in 3.2% in simple technique and 5.6% in classical technique (p=0.662). Retroperitoneal insufflation was seen in 6.5% in simple technique and 5.6% in classical technique (p=0.842). No failed pneumoperitoneum was observed in both groups. Conclusion Simple technique is as effective, reproducible and safe method as classical technique of creating closed pneumoperitoneum.

Objective To compares conventional piecemeal and en bloc resection techniques in terms of detrusor muscle presence in resected specimens, surgical safety, and feasibility. Method A prospective comparative study conducted from April 2024 to March 2025 included patients with up to three bladder tumors, measuring ≤ 3 cm, who were alternately assigned to undergo either conventional piecemeal resection or en bloc resection. The primary outcome was the presence of detrusor muscle in the resected specimen. Secondary outcomes included operative time duration, bladder perforation, and obturator reflex. The quality of tissue was assessed by pathologists using a Likert scale. Result Eighty-seven patients were included, 43 in the conventional and 44 in the en bloc group. The baseline characteristics and tumor size were comparable. Presence of detrusor muscle in specimens was higher in en bloc group (97.7% vs 83.7%; p = 0.030). Operative duration was shorter in the en bloc group (35.55 minutes vs 43.42 minutes; p = 0.001). A case of bladder perforation was observed in the conventional group. Pathologists observed better specimen orientation and architecture in the en bloc group. Presence of tumor in re-TURBT was 16.0% in the en bloc group and 28.6% in the conventional group (p=0.497). Conclusion En bloc resection yielded a higher presence of detrusor muscle and shorter operative duration with better specimen quality compared to conventional piecemeal resection for tumor ≤ 3 cm.

Buccal mucosa grafts (BMG) are a popular choice for substitution urethroplasty due to their favorable outcomes. This study evaluates the feasibility, safety, and acceptance of harvesting buccal mucosa grafts under local anesthesia. Objective To assess feasibility, safety and acceptance of Buccal mucosa harvest under local anesthesia. Method A prospective observational hospital based study to evaluate outcomes of substitution urethroplasty using buccal mucosa grafts (BMG) under local anesthesia. Result Of the 40 patients, 28 had unilateral graft harvests, while 12 had bilateral procedures. The mean graft length obtained was 5.65 cm. Postoperatively, patients experienced a quick recovery, with full mouth opening achieved within an average of 2.78 days and resumption of normal eating within 2.6 days. Minor complications included oral swelling in 15% of cases and food residue in 12.5%. Although 87.5% of patients reported pain at the perineal wound site, the overall pain score averaged 3.58, indicating manageable discomfort. Importantly, 92.5% of patients expressed a willingness to undergo the procedure again if necessary. Conclusion These findings suggest that buccal mucosa graft harvest under local anesthesia is both feasible and well-tolerated. The procedure appears to be a safe alternative to regional or general anesthesia, with minimal complications and a high level of patient acceptance. Future randomized controlled trials comparing local anesthesia to regional or general anesthesia could provide additional insights and further validate these findings. This study contributes to the growing body of evidence supporting the use of local anesthesia in urethral stricture surgery, offering a practical approach to managing this condition effectively.

Transurethral vaporisation of prostate is one modality of minimal invasive management of benign enlargement of prostate. This study assesses the efficacy and safety of transurethral vaporisation of prostate in small volume prostate. Objective To assess the efficacy and safety of bipolar plasma vaporisation of small volume prostate (Prostate Volume less than 40 grams). Method A total of 40 patients with prostate volume less than 40 grams and indications for operative management of benign enlargement of prostate were included. Patients with prior prostate surgery, urethral stricture surgery, presence of vesical calculus, urethral stricture and neurogenic bladder were excluded. Preoperative prostate size was assessed by transrectal ultrasonography. Comparison of preoperative and postoperative hemoglobin, sodium, international prostate symptom score and maximum flow rate was done. Perioperative complications were documented. Result The mean age of patients was 66.88 ± 9.09 years and the mean size of prostate was 32.52 ± 4.66 grams. Significant improvement in IPSS (preoperative 22, postoperative 9) and Qmax (preoperative 8.4 ml/min, postoperative 18.5 ml/min) was noted. There was significant drop in hemoglobin (p < 0.001) but no patients required blood transfusion. There was significant drop in sodium (p < 0.001) but no patients developed transurethral resection syndrome. Most complications were Clavien grade I. Two patients required recatheterization and all were catheter free on follow up. Two patients developed urethral stricture. Conclusion Bipolar transurethral vaporisation of Prostate is effective and safe treatment option for prostate volume less than 40 grams.
