Miniaturized percutaneous nephrolithotomy versus retrograde intrarenal surgery in the treatment of renal stones with a diameter <15 mm: A 3-year open-label prospective study

Aim: The aim of this study is to compare the outcomes of miniaturized percutaneous nephrolithotomy (mini-perc) and retrograde intrarenal surgery (RIRS) in management of renal stones with a diameter <15 mm. Materials and Methods: This was an open-label prospective study that included a total of 80 cases underwent mini-perc (n = 40) and RIRS (n = 40) between July 2014 and August 2017. The primary outcome objective was stone-free rate, retreatment rate, complications, hospital stay, operative time, and reduction in hemoglobin level. Data were analyzed using SPSS version 16.0 Software. Results: Overall, 80 patients were enrolled in this study. The mean age was 40.12 and 38.20 years, and the mean stone size was 1.15 and 1.30 cm in mini-perc and RIRS group, respectively. Majority of the study participants were males. Overall, mini-perc and RIRS had stone clearance rates of 100% and 95.4%, respectively. Two patients required retreatment in RIRS group. The duration of hospital stay and the rate of complication was similar in both the groups. Operative duration was more in RIRS group. Decrease in hemoglobin level was more in mini-perc group. Conclusions: Results demonstrated that both modalities were associated with high stone clearance rates with minimal complications. RIRS was associated with less reduction in hemoglobin and could be used as standard treatment modality for small renal calculi

Evaluation of stone volume and its relationship with surgical outcomes in patients with staghorn calculi

Introduction: Urolithiasis is one of the most common renal diseases with a significant burden on health-care system worldwide. Here, we evaluated the stone volume and its relationship with duration of operation, blood loss, and total stone clearance in patients with staghorn calculi. Materials and Methods: This was a prospective, single-center study conducted from October 2015 to September 2017. Patients of either sex aged more than 18 years of age with a confirmed diagnosis of staghorn calculus were eligible to participate in the study. Eligible patients were divided into three groups based on stone volume (assessed by three-dimensional computed tomography): Group 1 (≤5000 mm3), Group 2 (>5000 to ≤20,000 mm3), and Group 3 (>20,000 mm3). Results: A total of 85 patients were enrolled in the study (Group 1, n = 9; Group 2, n = 66; and Group 3, n = 10). The mean age was 43.68 years, and 62.4% of patients were male. The mean operative time increased significantly from Groups 1–3, (31.67, 60.14, and 92.30 min, respectively). The mean pre- and postoperative hematocrit was highest in Group 3 (2.82%) (P < 0.0001). Overall, the correlation between stone volume and operative time and difference in hematocrit showed a positive relationship. A total of five patients had residual calculus, and only four patients reported complications. Conclusions: The results showed that patients with larger stone volume need more operative time and may have more blood loss

Does urodynamics study help in evaluation and prognosis of treatment in benign prostatic hyperplasia with diabetes mellitus?

Aims: The aim is to study the clinical significance of urodynamics study (UDS) in patients of benign prostatic hyperplasia (BPH), with and without diabetes mellitus (DM) and to predict the outcome of surgical depending on UDS findings. Materials and Methods: A total of 120 BPH patients were studied and divided into two groups, BPH with DM and without DM. Initial evaluation, diagnostic tests, and urodynamic examination were done in all patients, and results were statistically analyzed. Results: There was no significant difference of age and prostate volume in both groups (P > 0.05), but there was a significant increase in symptom score in patients of BPH associated with DM (P < 0.05). Bladder outlet obstruction (BOO) was found in majority of patients in our groups (96.66%) with good detrusor function. Out of 120 patients, 6 patients (2 patient in BPH group and 4 patients in BPH with DM group) had detrusor underactivity (DU). There was a significant difference in the International Prostate Symptom Score, quality of life, peak flow rate, and postvoid residual urine, pre- to post-operatively in each group (P < 0.05). Out of the 6 patients who had DU, 4 patients (1 patient in BPH group and 3 patients in BPH with DM group) showed improvement in their flow rate and symptom score. Conclusion: DM in cases of BPH patients is not the prominent factor in deciding surgical treatment. It is the severity of BOO which determines the treatment and its outcome. UDS is an invasive and costly test and does not appear to be mandatory in clinically significant BPH even if associated with DM

Comparative evaluation of upper versus lower calyceal approach in percutaneous nephrolithotomy for managing complex renal calculi

Introduction: Percutaneous nephrolithotomy (PCNL) is the treatment of choice for staghorn and large renal stones. The success of PCNL is highly related to optimal renal access. Upper calyceal puncture being more difficult and more demanding have relatively few studies presented. Aims and Objectives: This prospective study was carried out to evaluate the effectiveness and safety of upper calyceal versus lower calyceal puncture for the removal of complex renal stones through PCNL. Materials and Methods: A total of 94 patients underwent PCNL for complex renal stone in our institute. Fifty-one of them underwent lower calyceal, while 43 underwent upper calyceal puncture. The two approaches are compared as per total duration of surgery, intraoperative blood loss, infundibular/pelvic tear, rate of complete clearance and rate of postoperative complications (pulmonary, bleeding, fever and sepsis, etc.). Observation and Results: In our study, the success rate was 76.47% for those in the lower, 90.70% for those in the upper calyceal access group. Thoracic complications (hydrothorax) occurred to 1 patient in upper calyceal supracostal access group. Bleeding requiring blood transfusion happened to 5 patients in lower calyceal access and 1 in upper calyceal group. Conclusion: In our study for the management of complex renal calculi, we conclude that in a previously unoperated kidney, upper calyceal puncture through subcostal or supra 12 th rib is a feasible option minimizing lung/pleural rupture and gives a better clearance rate. We suggest that with due precautions, there should not be any hesitation for upper calyceal puncture in indicated patients

Single center experience of primary hypospadias repair

Introduction: Hypospadias is a complex congenital deformity which requires meticulous surgical technique. Several techniques have been advocated during the past 150 years to address chordee and construction of neourethra. This study highlights the surgical techniques and experience with primary hypospadias cases. Materials and Methods: A total of 65 patients aged ranges from 1 to 18 years underwent primary hypospadias repair at our center from August 2007 to December 2012. Exclusion criteria - previous surgical attempt or with incomplete follow-up. Patients with inadequate phallic size and age <12 years were administered injection testosterone (Testoviron) prior to the surgery. Patients with significant chordee underwent chordee correction followed by urethral reconstruction by either tubularized incised plate (TIP) or on-lay flap repair/dartos flap repair. In all the patients, infant feeding tube was kept per urethrally for 3 weeks and was removed between the post-operative day 18 th and 21 st day. Results: Out of 65 patients, 24 patients underwent TIP. A total of 41 patients underwent on-lay flap repair; of this six patients of midscrotal/perineal hypospadias underwent a combination of paraurethral skin and on-lay flap repair. Chordee correction was done in all the five cases of chordee without hypospadias (congenital short urethra) and dysplastic, transparent urethra repaired with on-lay flap repair. In our study, complications like flap necrosis and fistula were seen in 10 cases and other minor complications like superficial epidermal sloughing were seen in 13 cases which healed with epithelialization. Meatal stenosis was more commonly observed with TIP (four cases) and in two cases of on-lay repair. Conclusion: Historically, hypospadias surgery was regarded as non-rewarding surgical reconstruction due to higher complication and failure rates. For hypospadias, if planned properly, primary single stage repair; acceptable surgical success is an achievable target

Uroflow nomogram for healthy, 15-40 year old Indian men

Introduction: Uroflowmetry is the objective method of measuring rate of urine flow. Nomograms are required to observe the change in flow rates at different voided volumes (VVs) and the use of which overcomes the limitation of referencing flow rates to any single VV. The purpose of the present study was to construct the Indian uroflow nomogram for adult healthy males between 15-40 years of age. Methods: A total of 1000 healthy males between 15 and 40 years of age were included in the study. Exclusion criteria were any urinary symptoms or urological intervention. Parameters analyzed statistically were age, peak flow rate (Q max ), average flow rate (Q avg ), and VV. A nomogram was drawn for the fitted regression model. Results: The mean age was 27.26 ΁ 6.71 years. The mean Q max , Q avg , and VV were 24.32 ΁ 3.50 ml/s, 9.45 ΁ 2.55 ml/s, and 420.93 ΁ 97.89 ml, respectively. The correlation between flow rates and VV was statistically significant, indicating that the higher the VV, the higher the flow rates. A negative significant correlation of Q max with age was seen in our study. We observed a decline of Q max by 1 ml/s/decade. The relationship of Q max with VV is in linear progression up to 600 ml, and then it becomes a plateau and with higher VV it declined. Conclusion: Q max exhibits significant correlation with VV and age. A nomogram was constructed to attain normal reference values of flow rate over different VVs

Use of parenteral testosterone in hypospadias cases

Objectives: The aim was to evaluate the effect of parenteral testosterone on penile length, preputial hood, vascularity of dartos pedicle in patients with hypospadias. Materials and Methods: A total of 42 patients with hypospadias were included in this study. Injection aquaviron (oily solution each ml containing testosterone propionate 25 mg) was given deep intramuscularly in three doses with an interval of 3 weeks before reconstructive surgery at the dose of 2 mg/kg body weight. Preoperatively penile length, transverse preputial width and diameter at the base of the penis were measured. Basal testosterone levels were obtained before the institution of therapy and on the day of operation. Results: Following parenteral testosterone administration, the mean increase in penile length, transverse preputial width and diameter at the base of penis was 1.01 ± 0.25 cm (P < 0.001), 1.250 ± 0.52 cm and 0.61 ± 0.35 cm, respectively, (P < 0.001). Serum testosterone level after injection was well within normal range for that age. Conclusion: Parenteral testosterone increased phallus size, diameter and prepuce hypertrophy without any adverse effects. However, due to lack of a control group we cannot make any inferences. Controlled studies are required to establish the benefits of parenteral testosterone

Prospective Randomised Controlled Trial Comparing Sub-Epididymal Orchiectomy Versus Conventional Orchiectomy in Metastatic Carcinoma of Prostate

Androgen blockade (surgical or medical castration) is a standard procedure for patients with metastatic carcinoma prostate. Sub-epididymal orchiectomy involves removal of testis leaving behind epididymis. This epididymal stump over a period gives a pseudo testicular feel within the scrotum. We present a prospective randomized study to assess the functional utility of this procedure and compare it with total orchiectomy in terms of achieving castrate levels. From July 2005–Jan 2008, 60 patients with metastatic carcinoma prostate were alternately randomised and allotted to two groups, 30 underwent sub-epididymal orchiectomy (group A) and remaining 30 (group B) underwent total orchiectomy. Age: 56–80 years. Serum PSA: 55–268 ng/ml. Preoperative serum testosterone: Group A—300–650 ng/ml and group B—320–640 ng/ml. Postoperative serum testosterone: group A—2–18 ng\ml and group B—7–15 ng\ml on day 7 after surgery. Operating time—26–40 mins for group A and 20–34 mins for group B. Follow up—6 weeks and 3 months. At 3 months patients were asked to grade appearance of scrotum for asthetic value on a scale of 1–100 using visual analogue score. Postoperative serum testosterone reached castrate levels in seven days (both groups). Duration of surgery in both groups was comparable. Complications—wound infection in 1 patient (group A) & 1 scrotal hematoma (group B). Satisfaction score for group A (83.5 ± 9.7) was significantly (p < 0.05) better (95%CI—18.58–28.42), compared to that of group B (60 ± 9.4) by using‘t’ test. Sub epididymal orchiectomy is comparable to total orchiectomy in terms of achieving castrate levels with similar operating time. It has significant advantage in terms of mental satisfaction to patients. It is a simple and safe procedure that can be conveniently performed in an outpatient clinic setting using pure local anaesthesia
