ObjectivesTo evaluate factors contributing to bleeding after percutaneous nephrolithotomy (PCNL) and ways of managing this complication, as bleeding is a serious sequela that requires prompt management.Patients and methodsThe demographic and procedural data of 200 patients, who underwent unilateral PCNL during a 20-month period, were prospectively collected. Preoperative, operative, and postoperative details were recorded. The preoperative variables analysed included: age, sex, body mass index (BMI), the presence of hypertension, diabetes mellitus, serum creatinine, degree of hydronephrosis, previous ipsilateral open renal surgery, stone size and complexity. The operative variables analysed included: number of tracts, operative time, size of Amplatz sheath, type of anaesthesia, and complications such as calyceal and pelvic perforation.ResultsThe variables of age, sex, BMI, diabetes, hypertension, and a preoperative creatinine level of >1.4 mg/dL had no significant effect on blood loss (all P > 0.05). However, the rate of bleeding was significantly higher (P ⩽ 0.05) in patients who had a history of previous open renal surgery, intraoperative pelvicalyceal perforations, and Guy’s Stone Score (GSS) grade 3 and 4 complex stones; however, absence of hydronephrosis, larger stone size, operative time (>83 min), more than one puncture, and size of the Amplatz sheath (26–30 F) did not maintain their significance in multivariate analysis.ConclusionAccording to our present results stone complexity (GSS grade 3 and 4), history of ipsilateral renal stone surgery, and occurrence of intraoperative pelvicalyceal perforation are alarming variables for post-PCNL bleeding.

ObjectivesTo evaluate the safety and effectiveness of ureteric stenting with a JJ stent in pregnant women, to relieve renal obstruction and intractable flank pain.Patients and methodsAll pregnant patients presenting with intractable flank pain, with or without complications, to a tertiary national teaching hospital in Kurdistan/Iraq, and necessitating ureteric stenting with a JJ stent, were prospectively assessed for this study between March 2008 and March 2010.ResultsIn all, 30 pregnant patients presented with intractable flank pain necessitating JJ ureteric stenting during the 25 months. Intractable flank pain (23 patients, 77%) was the most common indication for ureteric stenting, followed by flank pain with clinical sepsis (six, 20%). All pregnant women had hydronephrosis on ultrasonography (US), and 12 (40%) had evidence of coexisting renal stones on US. All ureteric stents were inserted successfully. The mean (range) indwelling time was 47.4 (3–224) days. Radiologically, 14 (47%) and 15 (50%) had complete resolution of the hydronephrosis on follow-up US in late pregnancy and in the early postnatal period, respectively. Two-thirds of patients had a clinical improvement immediately (15, 50%) and soon after (five, 17%) surgery. Stent encrustation (three, 10%), stent migration (three, 10%) and stent irritation (five, 17%) were reported as complications. The post-natal evaluation confirmed that half the patients had urinary calculus disease.ConclusionUreteric stenting during pregnancy can be safe, with no intraoperative imaging and even under local anaesthesia. It provides good symptom relief and has a low complication rate. We therefore advocate it as a first-line treatment in pregnant women with therapy-resistant flank pain.

Background and Objectives:To evaluate the usefulness of laparoscopic varicocelectomy in the management of chronic scrotal pain.Methods:Between 2009 and 2011, 48 patients in total were treated with laparoscopic varicocelectomy for dull scrotal pain that worsened with physical activity and was attributed to varicoceles. All patients were followed up at 3 and 6 months and biannually thereafter with a physical examination, visual analog scale score, and ultrasonographic scan in selected cases.Results:The mean age was 38.2 years (range, 23–54 years). The mean follow-up period was 19.6 months (range, 6–26 months). Bilateral varicoceles were present in 7 patients (14.6%), and a unilateral varicocele was present in 41 (85.4%). The varicocele was grade 3 in 27 patients (56.3%), grade 2 in 20 (41.6%), and grade 1 in 1 (2.1%). The mean preoperative visual analog scale score was 4.8 on a scale from 0 to 10. The mean postoperative visual analog scale score at 3 months was 0.8. After the procedure, 42 patients (87.5%) had a significant improvement in the visual analog scale score (P < .001); 5 (10.4%) had symptom improvement, although it was not statistically significant; and 1 (2.1%) remained unchanged. During follow-up, we observed 5 recurrences (10.4%) whereas de novo hydrocele formation was identified in 4 individuals (8.3%).Conclusion:Laparoscopic varicocelectomy is efficient in the treatment of symptomatic varicoceles with a low complication rate. However, careful patient selection is necessary because it appears that individuals presenting with sharp, radiating testicular pain and/or a low-grade varicocele are less likely to benefit from this procedure.

Background: Ipsilateral renal agenesis associated with seminal vesicular cysts is an uncommon finding. Zinner syndrome is a rare variant of wolffian duct anomalies with a triad of seminal vesicle cyst, ipsilateral renal agenesis, and male fertility problems due to ejaculatory duct obstruction (EDO).Case Presentation: A 28-year-old man with 6 years history of primary infertility presented with left-side lower abdominal pain. A palpable cystic mass was found on digital rectal examination. Semen analysis revealed low volume ejaculate azoospermia. Abdominal ultrasonography revealed a single right kidney and transrectal ultrasonography showed an evidence of left EDO. Transurethral resection of the ejaculatory duct was performed. Semen analysis after 2 weeks showed normal sperm count (23M) and acceptable progressive motility (24%). Eight weeks later, his wife was pregnant with a 7-week viable fetus.Conclusion: Although not a common disease, a careful physical examination and thorough semen analysis interpretation should guide clinicians to diagnose a surgically treatable syndromic cause of male infertility.
