A Prospective Study Comparing Quality of Life after Laparoscopic Donor Nephrectomy versus Open Donor Nephrectomy.

Laparoscopic donor nephrectomy (LDN) has advantages over open donor nephrectomy (ODN), with less bleeding and pain, and earlier discharge. However, the quality of life (QOL) has not been compared between these techniques. All consecutive donors undergoing left LDN or ODN from 2013 to 2015 at our center were included. The donors' QOL was measured with the brief World Health Organization QOL (WHOQOL-BREF) and the Hospital Anxiety and Depression Scale (HADS) questionnaires preoperatively and at 3 and 6 months postoperatively. Cosmesis was measured by the body image questionnaire, and patient satisfaction was scored on a verbal rating scale at 3 and 6 months. Of the 264 donors, 228 met the inclusion criteria (100 - LDN and 128 - ODN). The LDN group showed no difference in WHOQOL-BREF scores at 3 months, and significant improvements in the psychological and social domains at 6 months versus the baseline. The ODN group showed a significant decrease in the physical, psychological, and environmental domains at 3 and 6 months versus the baseline. Compared with the ODN group, the LDN group had better QOL scores at 3 and 6 months in all domains. The responses to the HADS questionnaire were similar between the groups at all time points. The mean body image, cosmesis, and satisfaction scores were significantly better in the LDN group. LDN minimized the negative effects of surgery on the donors' QOL, with improvements in the long-term psychological and social aspects versus the baseline. LDN was more cosmetic and was associated with higher satisfaction than ODN.

Role of laparoscopy in the era of robotic surgery in urology in developing countries.

With the rapid expansion of robotic platforms in urology, there is an urgent and unmet need to review its cost and benefits in comparison to the traditional laparoscopy, especially in reference to a developing country. A nonsystematic review of the literature was conducted to compare the outcomes of pure laparoscopic and robot-assisted urologic procedures. Available literature over the past 30 years was reviewed. Robot-assisted surgery and laparoscopy were found to have similar outcomes in the areas of radical prostatectomy, partial and radical nephrectomy, radical cystectomy, retroperitoneal lymph node (LN) dissection, inguinal LN dissection, donor nephrectomy, and kidney transplantation. Robot-assisted surgery was found to be significantly costlier than pure laparoscopy. In the absence of a clear advantage of robot-assisted surgery over pure laparoscopy, lack of widespread availability and the currently prohibitive cost of robotic technology, laparoscopic urological surgery has a definite role in the developing world.

Establishing a Robot-Assisted Kidney Transplant Program: Independent Evaluation of the Learning Curve and Surgical Nuances.

Background: Robot-assisted kidney transplantation (RAKT) is a technically challenging procedure and there has been limited reporting of its learning curve (LC), mostly by a single surgical working group. The aim of the current study was to perform an independent analysis of LC and describe our modifications in the technique of RAKT. Materials and Methods: All consecutive cases performed at our center from April 2016 to March 2020 were reviewed. LC was analyzed by using the cumulative summation method for total anastomosis time (technical outcome) and serum creatinine at days 7 and 30 (functional outcome). Patient safety was assessed by using Shewhart control charts, and a comparison of safety outcomes before and after achieving LC was done by using Chi-square or Fischer exact test as appropriate. A descriptive review of technical modifications made during our experience was conducted. Results: Ninety patients underwent robot-assisted renal transplant during the study period. LC was crossed at 24 cases (total anastomosis time) and 15 to 25 cases (serum creatinine). Shewhart control charts showed that total anastomosis time remained below alert/alarm line in 94.4%/98.9% cases, with the alert line being crossed a significantly greater number of times before the LC. Serum creatinine values remained below alert/alarm line in 85.5%/90% cases at day 7 and 92.2%/96.7% cases at day 30, with no difference made due to LC. Key technical modifications included arterial and ureteric spatulation at bench, use of polypropylene 5 to 0 holding stitch in graft vessels to facilitate intraoperative handling, keeping anterior arterial wall smaller to visualize posterior arterial wall anastomosis, and leaving a small amount of fatty tissue on the supero-lateral surface of the kidney for handling after jacket removal. Conclusion: Our LC of RAKT was crossed at 24 cases (technical outcome) and 15 to 25 cases (functional outcome). We have also detailed valuable technical modifications in the procedure.

Comparative analysis of outcomes and long-term follow-up of robot-assisted pediatric kidney transplantation, with open counterpart.

How does the robotic kidney transplant fare against the open technique, in pediatric patients? No one knows. To address this question, this study compares the outcomes of robotic kidney transplants, with those of open transplant in these patients. This study was a retrospective analysis of outcomes (renal function and complications), of all pediatric patients (<18 years of age), who underwent kidney transplant at our institute, after 2014, till their last follow-up. Fisher's exact test was used to compare proportions. Continuous variables were analyzed using Mann-Whitney test. P value of <.05 was considered significant. Of the twenty-five patients included, 21 belonged to open group, and 4 to the robotic group. Patients in the robotic group had significantly higher Re-WIT (P value .002) and had lower analgesia requirement (P value .04). Median follow-up period was 31 months. Both groups were comparable in terms of length of hospital stay, blood transfusion, and renal function post-operatively till their last follow-up. Three patients in the open group had surgical site infection as compared to none in the robotic group. All the patients had functioning grafts till their last follow-up. Robotic transplant is safe and delivers functional results similar to open technique, with lesser pain and better cosmesis. Longer Re-WIT in robotic transplant has no impact on post-operative renal function. Ours is the first known effort to compare robotic technology with the established open technique of transplant in this population. A prospective randomized controlled trial should refine the results of the present study.

Management of donor kidneys with double renal arteries with significant luminal discrepancy: A retrospective cohort study.

INTRODUCTION: Side-to-side pantaloon anastomosis for renal grafts with double renal arteries (RA) with significant luminal discrepancy between graft arteries has not been reported. We hypothesized that the pantaloon technique is feasible and safe in these cases. MATERIALS AND METHODS: A retrospective review of all consecutive, open, live-related renal transplants with double RA with significant luminal discrepancy performed at our center from January 2014 to September 2018 was undertaken. Significant luminal discrepancy was defined as smaller RA constituting 30% ± 5% of total RA diameter on preoperative computed tomography angiogram. Three groups were defined: Group A - pantaloon anastomosis, Group B - end-to-side anastomosis of smaller to main RA, and Group C - separate implantation of each artery. The primary objective was to study feasibility and safety of pantaloon anastomosis measured by recipient serum creatinine levels, Doppler ultrasound, and vascular complications (vascular thrombosis and anastomotic bleed). Secondary objectives included measurement of cold ischemia time, warm ischemia time in recipient (WIR), and nonvascular recipient complications. RESULTS: Fifty-eight recipients had donors with double RA with significant luminal discrepancy. Group A - included 40, Group B - 5, and Group C - 13 patients. Recipient creatinine at day-7, - 30, and - 90 were similar among the groups. The 30-day perioperative complication rate was also similar. Group A and B had significantly lower WIR and higher cold ischemia time compared to Group C. CONCLUSION: Pantaloon anastomosis is feasible in renal grafts with double RA with significant luminal discrepancy and offers advantage of lower WIR compared to separate implantation technique.

Primary Bladder Neck Obstruction in a Young Woman: A Novel Technique of Bladder Neck Incision Using Holmium Laser.

Background: Management of primary bladder neck obstruction (PBNO) in women is difficult. Surgical treatment in the form of bladder neck incision (BNI) is indicated in many cases. There is no defined consensus on the best surgical technique of BNI in women. We present a novel technique of BNI in such cases using pediatric cystoscope and holmium laser, which is a promising alternative to the existing management techniques. Case Presentation: A 28-year-old lady complained of obstructive lower urinary tract symptoms. Serum biochemistry revealed azotemia. Further investigation utilizing a micturating cystourethrogram showed a closed bladder neck, and urodynamic studies revealed a high bladder outlet obstruction index suggestive of PBNO. BNI was effectively performed using pediatric cystoscope and holmium laser at 3, 9, and 12 o'clock positions. Postoperatively the patient had improving renal function and clinical improvement. Conclusion: Use of pediatric cystoscope with holmium laser for BNI in females is a novel technique that offers the advantage of higher maneuverability in the female urethra, precise incision with protection of external sphincter from thermal damage, and avoidance of the complication of vesicovaginal fistula caused by posterior incisions.

Randomized controlled trial to compare outcomes with and without the enhanced recovery after surgery protocol in patients undergoing radical cystectomy.

INTRODUCTION: Very few randomized controlled trials are available globally to support routine use of enhanced recovery after surgery (ERAS) protocol after radical cystectomy (RC), and none so far has been conducted in the Indian subcontinent. The aim of the present study was to evaluate hospital stay and 30-day perioperative outcomes following RC with the implementation of the ERAS protocol. MATERIALS AND METHODS: Fifty-four patients undergoing open RC were randomized to ERAS versus conventional surgical care (CSC) at our center from April 2017 to May 2018. Key interventions included avoidance of mechanical bowel preparation, early nasogastric tube removal, early enteral feeding, and early obligatory ambulation. Follow-up was done till 30-day postoperatively or till discharge, whichever longer. RESULTS: Twenty-seven patients in each group were analyzed. The demographic profile of the groups was similar. Length of stay in each group (8 days [5-57] ERAS vs. 9 days [5-31] CSC group, P = 0.390) was similar, with time to recovery of bowel function being significantly less in ERAS group (12 h [12-108] vs. 36 h [12-60] for bowel sounds [P = 0.001], 48 h [12-108] vs. 72 h [36-156] for passage of flatus [P = 0.001], and 84 h [36-180] vs. 96 [60-156] for passage of stools [P = 0.013]). Perioperative complication rate (12 patients (44.4%) vs. 14 (51.9%), P = 0.786) was similar. CONCLUSIONS: ERAS protocol leads to faster bowel recovery compared to conventional care in patients undergoing open RC but fails to demonstrate a shorter length of stay and lower complication rate.

'Poles apart presentation': diagnosis and management of iatrogenic posterior urethral false tract in cases of pelvic fracture urethral injury.

Iatrogenic creation of false tract in posterior urethra while managing a case of pelvic fracture urethral injury is a dreadful complication. The spectrum of presentation ranges from complete urinary incontinence to urinary retention. We describe three such cases created due to railroading or attempted repair. Case 1 presented with total urinary incontinence following open perineal urethroplasty for posterior urethral trauma while two cases presented with failure to void after endoscopic or open surgical management for the same. One patient was managed with endoscopic resection of the septum between the false passage and true posterior urethra; two cases required redo urethroplasty. All patients voided well postoperatively and were continent. Surgeon experience and meticulous endoscopic evaluation are the keys to success. Forceful attempt at per urethral catheter placement in the acute setting should be avoided. Blind railroading of the catheter and unnecessarily forceful passage of suprapubic metal bougie during urethroplasty should be condemned.

Spontaneous prostatic haematoma in a case of benign prostatic hyperplasia.

A 61-year-old man presented with urinary retention with obstructive uropathy (urea/creatinine: 126/9.2 mg/dL) secondary to a large prostatic haematoma while being medically managed for benign enlargement of the prostate. The patient did not have any fever or local symptoms and the prostate was enlarged and non-tender on examination. Ultrasound and MRI of the pelvis showed a 9.4×10.4×11.1 cm sized prostatic haematoma seen displacing and compressing the urinary bladder anteriorly with bilateral hydroureteronephrosis. The patient was managed with per-urethral catheterisation, haemodialysis and injectable antibiotics. Percutaneous pigtail placement into the prostatic haematoma led to gradual drainage of the haematoma with improvement in the renal parameters. Definitive surgery in the form of transurethral resection of the prostate was done at a later date. Intraoperatively multiple encapsulated cavities containing organised clots were deroofed. On follow-up, the patient did well and had good urinary flow and normal renal parameters.

A rare case of persistent nephropleural fistula following percutaneous nephrolithotomy.

Nephropleural fistula following percutaneous nephrolithotomy (PCNL) is a very rare complication and there are only a few case reports available in the literature. We present a case of a 65-year-old male patient with a right staghorn renal calculus and a left upper ureteric calculus who developed a right nephropleural fistula following right-sided PCNL. The patient required intercostal tube drainage. The cause of the fistula was identified to be a superior calyceal infundibular obstruction due to tiny residual stone fragments and oedema, which was endoscopically dilated, and the fistula subsequently healed. Urinary diversion using chest drainage and percutaneous nephrostomy followed by infundibular dilation and removal of secondary stones allowed the successful closure of the nephropleural fistula in our case.

Synchronous urinary bladder metastasis of chromophobe renal cell carcinoma.

Urinary bladder metastasis in patients with renal cell carcinoma is rare and until now <70 cases have been documented in literature. Majority of these reported cases were histologically clear cell variant of renal cell carcinoma. Urinary bladder metastasis of chromophobe variant of renal cell carcinoma is extremely rare and is limited to only isolated case reports. We present here a case of a man aged 24 years who was diagnosed to have a left renal mass and right renal calculi on evaluation for complaints of left-sided abdominal pain and was incidentally detected to have suspicious bladder lesions during cystoscopy. Postoperative histopathology from the renal mass as well as the urinary bladder lesions showed chromophobe variant of renal cell carcinoma. The patient did not develop any recurrence on follow-up.

Nimodipine down-regulates CGRP expression in the rat trigeminal nucleus caudalis.

L-type calcium channel blockers like verapamil are used in the prophylaxis of migraine. However, their effect on the expression of CGRP in the trigeminal nucleus caudalis (TNC) is unknown. It is important because an earlier study had shown that olcegepant, a CGRP receptor antagonist, acts at the level of the trigeminal spinal nucleus rather than the trigeminal ganglia. Nimodipine was used in the present study as it crosses the blood-brain barrier. The objective of the study was to determine the pattern of expression of calcitonin gene-related peptide (CGRP) in the TNC after administration of nimodipine and/or morphine. Wistar rats were injected with saline, morphine, nimodipine or morphine + nimodipine for 14 days. Subsequently, the lowest part of the medulla oblongata containing the spinal nucleus was removed and processed for immunohistochemical localization of CGRP. The density of expression was quantified using Image J software. The results were statistically analyzed. CGRP expression was noted over the superficial part of the TNC, which decreased significantly after nimodipine administration. Conversely, morphine produced an up-regulation. The expression was unchanged with reference to saline in the morphine + nimodipine treated group. Decreased expression of CGRP in the trigeminal nucleus caudalis after nimodipine is being reported for the first time. Also, whether CGRP expression can be used as a marker for predicting the therapeutic efficacy of an anti-migraine drug is currently being investigated.
