Mini-PCNL - a boon for CKD patients with nephrolithiasis.

Purpose: The prevalence of urinary stone disease in ESRD is 3.2%, leading to renal damage due to obstructive uropathy, infection, and frequent surgical intervention. PCNL, the gold standard for complex renal stone disease, has evolved with smaller access sheaths (14-20 F), improved optics, and fluoroscopic equipments. This study aims to assess the safety and feasibility of mini- PCNL in CKD patients with respect to postoperative outcome and its effect on stage of CKD. Patients and methods: This prospective study was conducted in the Department of Urology, Sher-I-Kashmir Institute of Medical Sciences, from January 2022 to October 2022. This study included adult patients with nephrolithiasis at CKD stage 3 or higher. The primary objective of this research was to assess the impact of mini-PCNL on renal function, specifically measuring changes in estimated glomerular filtration rate (eGFR) from baseline to a 6-month follow-up. The secondary objective was to evaluate the feasibility of mini-PCNL in CKD patients in terms of complications, stone clearance rate, and duration of hospital stay. Four variable Modification of Diet in Renal Diseases(MDRD) equation was used to calculate the estimated GFR(eGFR) of each patient and NKF/KDOQI classification system to classify the stage of CKD. Results: A total of 46 patients were included in the study. We found that for management of nephrolithiasis in CKD patients, mini-PCNL leads to significant improvement in eGFR at 6 months follow-up (mean difference = 14.25 ml/min/1.73 m2; p-value <0.01) with high stone-free rates (89.5%). The complication rates were comparable to standard PCNL. Conclusions: mini-PCNL is a bonanza for management of CKD patients with nephrolithiasis.

Zinner's syndrome: Masquerading as pyonephrotic ectopic kidney.

Zinner's syndrome is a rare developmental anomaly of Wolffian duct, comprising a triad of seminal vesicle cyst, ipsilateral renal agenesis and ejaculatory duct obstruction, first described by Zinner in 1914. Several aberrations have been reported like renal dysplasia, ectopic ureteric orifice in one of the derivatives of Wolffian duct. Usually it presents in second to fourth decade of life with symptoms of urinary bladder irritation/obstruction, cyst distension, ejaculatory duct obstruction. The diagnosis is principally based on imaging studies, usually confirmed by MRI. Treatment is based upon the persistent symptoms or complications related to it. Excision of cyst is gold standard.

Comparative study of tamsulosin versus tadalafil in benign prostatic hyperplasia patients with lower urinary tract symptoms. A prospective randomized study.

Introduction: Benign prostatic hyperplasia (BPH) is one of the common causes of lower urinary tract symptoms (LUTS) in aging men. Men with LUTS have a higher incidence of erectile dysfunction (ED), and LUTS themselves represent an independent risk factor for ED, triggering a significant negative impact on quality of life. Materials and Methods: A total of 92 patients were randomly assigned to two groups. Groups I and II had 45 and 47 patients, two patients from Group I and three patients from Group II did not follow and were excluded from the study. Patients in Group I received 0.4 mg of tamsulosin and Group II patients received 5 mg tadalafil. Patients were assessed at baseline, 3 months, and at 6 months after receiving treatment. Treatment efficacy was measured by a change in Qmax, post void residual urine (PVR), International Prostate Symptom Score (IPSS), and Sexual Health Inventory for Men (SHIM) score at 3 months and 6 months. Results: Baseline parameters between the two groups were similar. Mean Qmax improved by 7 ml/s at 3 months to 9.44 ml/s at 6 months in Group I versus 4.73 ml/s at 3 months to 6.46 ml/s at 6 months in Group II (P = 0.739). Mean PVRU decreased by 35.53 ml at 3 months to 47.23 ml at 6 months in Group I versus 44.98 at 3 months to 58.28 ml at 6 months in Group II (P = 0.102). IPSS score improved by 4.24 points at 3 months to 7.22 points at 6 months in Group I versus 4 points at 3 months to 5.02 points at 6 months in Group II (P = 0.336). SHIM score improved by 0.7 points 16.2 at 3 months to 0.8 points at 6 months in Group I versus 6.12 points at 3 months to 6.3 points at 6 months (P < 0.001). Conclusion: When both groups were compared, tadalafil showed statistically similar improvements in Qmax, PVRU, and IPSS score, but statistically significant improvement was observed with tadalafil in SHIM score compared with tamsulosin in treating LUTS secondary to BPH. Our study provides evidence that once daily tadalafil 5 mg is well tolerated and can be considered for the treatment of LUTS secondary to BPH especially in patient with ED.

Slowly developing urinothorax in a child due to intrapleural migration of DJ stent-a rare complication of percutaneous nephrolithotomy.

Percutaneous nephrolithotomy is usually considered as safe and effective in the management of renal stones in pediatric population. Urinothorax defined as presence of urine in pleural cavity is a rare complication of percutaneous nephrolithotomy. We present a rare case of slowly developing urinothorax in a 9-year-old boy following PCNL due to migration of DJ stent into the pleural cavity. The case was managed by intracostal tube drainage and repositioning of DJ stent.

Prostatic rhabdomyosarcoma in the adult, A case report.

Prostate embryonal rhabdomyosarcoma (ERMS) is a common tumour in infants and children, but it is rare in adults. It is characterized by a high degree of malignancy, both local rapid growth with formation of large pelvic masses, often leading to renal failure due to bladder outlet obstruction, and systemic spread, commonly to the lungs, liver and bone. We report on a case of a stage III prostate ERMS, approached with combined-modality treatment, with the administration of 5 courses of doxorubicin, ifosfamide and 2-mercaptoethane sulfonate sodium (mesna), with planned subsequent radiotherapy to the prostatic bed (60 Gy/30 fractions).

Outcome of dorsal buccal graft urethroplasty in female urethral stricture disease (FUSD); our institutional experience.

INTRODUCTION AND HYPOTHESIS: Female urethral stricture is a poorly studied disease entity. To date, its management has been poorly evaluated, with small numbers and various definitions of success. Treatment options traditionally have been urethral dilatation and/or self-catheterization with success rates ranging from only 14 to 49%. However, there has been increasing use of urethroplasty due to the improved success rate (70 to 100%). In this study we assessed the outcome of dorsal buccal mucosal grafts in female urethral stricture disease. MATERIALS AND METHODS: In our study we prospectively analyzed 25 female patients treated from 2014 to 2019 at our institute; ages ranged from 26 to 66 years. Dorsal buccal mucosal graft urethroplasty was performed in all patients. The pathology of female urethral stricture disease is unknown, and neither the pre- nor the intraoperative assessment allows determining the precise location and extent or the severity of urethral damage; therefore, we advocate extensive grafting of the entire urethra. Patients were followed every 3 months during the 1st year and then biannually with lower urinary tract symptom, uroflowmetry and post-void residual urine assessments. Stricture recurrence (failure) was defined as recurrence of symptoms, no change or reversal in Qmax and post-void residual urine values and failure of negotiation of a 17-Fr cystoscope. RESULTS: Success rate of our surgical intervention was > 90%. We observed that the mid-urethra was the most common location of the stricture. Stricture location was confined to the distal urethra in 12%, the mid-urethra in 16%, spanned the distal mid-urethra in 16%, spanned the mid-proximal urethra in 40% and spanned the pan-urethra in 16%. Mean stricture length was 1.8 (0.7-2.1) cm. Mean pre- versus postoperative Qmax was 5 ml/s versus 23.3 ml/s and mean residual urine was 178 ml versus 18.5 ml. Two patients had stricture recurrence at 3 months post-intervention. CONCLUSION: Dorsal buccal mucosal graft currently represents a prime choice for female urethral stricture reconstruction, keeping in view the advantages of the procedure such as easy availability of the graft and fewer donor site comorbidities. We emphasize upfront urethroplasty and extensive urethral grafting.

Transvaginal subfascial synthetic sling - "A novel technique" versus trans-obturator mid-urethral sling in female stress urinary incontinence: A comparative study.

BACKGROUND: To assess the treatment outcome and overall efficacy of the novel technique of a transvaginal subfascial synthetic sling (TVSS) in comparison to the standard trans-obturator tape (TOT-O) mid-urethral sling for female stress urinary incontinence (SUI). MATERIALS AND METHODS: The study included 206 female SUI patients managed at our institution between March 2015 and December 2019. The patients were randomly distributed into 2 comparable groups (Group A as TOT-O and Group B as TVSS) with respect to age, trouble due to SUI assessed with respect to degree of incontinence (number of episodes and diapers used per day), and body mass index (≤40 kg/m2), with 100 patients in the TOT-O group as group A and 106 patients in TVSS as group B. Preoperative variables related to the number of incontinent episodes and diapers usage were equal in both groups. The procedure was done under spinal anesthesia and results were assessed in terms of improvement in SUI as the primary outcome, any sexual dysfunction, complications, and overall satisfaction as secondary outcomes. RESULTS: Symptomatic improvement after the procedure was seen in all patients with complete resolution of symptoms in 91 patients (91.%) in the TOT-O group (group A) versus 96 patients (90.56%) in the TVSS (group B). Postoperative complications included urinary retention in 6% versus 5.6%, increased day time urinary frequency in 8% versus 6.6%, urge incontinence in 4% versus 2.8%, and groin/thigh pain in 12% versus 0.9%, respectively. Mesh incision was done in 1 (1%) versus none (0%), and local mesh excision for mesh erosion in 2 (2%) versus 1 (0.9%) at 3 months after the procedure in the TOT-O group and the TVSS group, respectively. The p value and Chi-Square test with respect to the clinical profile and satisfaction with respect to complete resolution of symptoms was calculated using Open EPI software which were insignificant. Sexual function (SF) was assessed using the Brief Index of SF for Women questionnaire. All the patients were satisfied with respect to SF at 6 months of follow-up. CONCLUSIONS: The TVSS as a novel technique for female SUI is less invasive, simpler to learn, with less postoperative pain with resolution of SUI, rapid recovery, and good personal satisfaction compared to the standard TOT-O in procedure.

Outcome of laparoscopic nephron sparing surgery using a Satinsky clamp for hilar control: a trusted tool (SKIMS experience).

BACKGROUND: Nephron sparing surgery is a well-established surgical procedure for patients with small/bilateral renal masses. During the procedure, hilar control can be achieved by using bulldog clamps individually on the renal vessels, the renal artery alone without clamping the vein, or a laparoscopic Satinsky clamp for en bloc hilar clamping. In our series, we described the outcome of laparoscopic nephron sparing surgery using a Satinsky clamp for hilar control. MATERIALS AND METHODS: All eligible cases with confirmed diagnosis of a renal mass were advised of nephron sparing surgery. The short-term outcomes were evaluated by warm ischemia time (using a Satinsky clamp especially when CT renal angiography was not available), average blood loss, and length of postoperative hospital stay. The oncological outcome was evaluated by noting the surgical margins of histopathological specimen, local recurrence, and distant metastasis. RESULTS: Of 30 cases 20 were male. The mean age was 54.25 years. On preoperative evaluation, 24 cases were T1a stage and the rest were 6 T1b stage. Four tumors were located in the upper pole, 4 in the posterior midpole, and 22 in the lower pole. Twenty-six patients had a low complexity score on RENAL scoring (ie, 4-6) and 4 patients a medium complexity score (ie, 7-9). Three patients were converted to open partial nephrectomy because of technical difficulty in intracorporeal suturing and difficulty in achieving hemostasis. Among these 3 patients, 2 patients had posterior base tumors and 1 had a lower polar tumor. Average blood loss was 350 ml, warm ischemia time was 28.46 minutes, and postoperative stay was 4.55 days. Of 30 specimens for histopathology, 23 (76%) were clear cell renal cell carcinoma (RCC), 4 (13%) were papillary RCC, 1 (3.3%) was chromophobe RCC, whereas 2 (6.6%) were benign (oncocytoma). Margins were free of tumors in all the patients with no recurrence in 2 years of follow-up. CONCLUSION: Laparoscopic partial nephrectomy by using a Satinsky clamp as a tool for en bloc hilar clamping in the proper axis at the hilum takes care of multiple vessels irrespective of size and number, particularly when renal angiography is not available. This technique of en bloc hilar clamping is quite useful especially in developing countries where robotic facilities are not available. The Satinsky clamp decreases blood loss and intraoperative time.

Surgical Outcome of Renal Cell Carcinoma with Tumor Thrombus Extension into Inferior Vena Cava and Right Atrium (Beating Heart Removal of Level 4 Thrombus): A Challenging Scenario.

AIM: "To evaluate oncological and surgical outcomes of different levels of tumor thrombus and tumor characteristics secondary to renal cell carcinoma (RCC)". MATERIALS AND METHODS: Retrospective review from 2013 to 2020 of 34 patients who underwent radical nephrectomy with thrombectomy for RCC with tumor thrombus extending into the inferior vena cava (IVC) and right atrium (RA) at our center. Level I and most level II tumors were removed using straight forward occluding maneuvers with control of the contralateral renal vein. None of the patients had level III tumor extensions in our study group. For level IV thrombus, a beating heart surgery using a simplified cardiopulmonary bypass (CPB) technique was used for retrieval of thrombus from the right atrium. RESULTS: " Of the 34 patients with thrombus", 19 patients had level I, 12 patients had level II, none had level III, and three patients had level IV thrombus. Two patients required simplified CPB. Another patient with level IV thrombus CPB, was not attempted in view of refractory hypotension intraoperatively. Pathological evaluation showed clear-cell carcinoma in 67.64%, papillary carcinoma in 17.64%, chromophobe in 5.8%, and squamous cell carcinoma in 8.8% of cases. Left side thrombectomy was difficult surgically, whereas right side thrombectomy did not have any survival advantage. Mean blood loss during the procedure was 325 mL, ranging from 200 to 1000 mL, and mean operative time was 185 min, ranging from 215 to 345 min. The immediate postoperative mortality was 2.9%. Level I thrombus had better survival compared to level II thrombus. CONCLUSION: Radical nephrectomy with tumor thrombectomy remains the mainstay of treatment in RCC with inferior venacaval extension. The surgical approach and outcome depends on primary tumor size, location, level of thrombus, local invasion of IVC, any hepato-renal dysfunction or any associated comorbidities. The higher the level of thrombus, the greater is the need for prior optimization and the adoption of a multidisciplinary approach for a successful surgical outcome.

Spontaneous adrenal hemorrhage during pregnancy: review of literature and case report of successful conservative management.

Spontaneous adrenal hemorrhage is an acute hemorrhage from the adrenal gland which occurs in the absence of trauma. The incidence of this condition during pregnancy is unknown. We describe a patient with massive unilateral adrenal hemorrhage which occurred during labor. The patient was successfully managed conservatively with complete resolution of the hematoma. A review of the literature of this rare condition is also presented.
